TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 4 10 StallGuard2 Load Measurement StallGuard2 provides an accurate measurement of the load on the motor. It can be used for stall detection as well as other uses at loads below those which stall the motor, such as CoolStep loadadaptive current reduction. (StallGuard2 is a more precise evolution of the earlier StallGuard technology.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) Status word SG Description 10-bit unsigned integer StallGuard2 measurement value. A higher value indicates lower mechanical load. A lower value indicates a higher load and therefore a higher load angle. For stall detection, adjust SGT to return an SG value of 0 or slightly higher upon maximum motor load before stall. 11 Range 0… 1023 Comment 0: highest load low value: high load high value: less load 4.

TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 13 4.3 Detecting a Motor Stall To safely detect a motor stall, a stall threshold must be determined using a specific SGT setting. Therefore, you need to determine the maximum load the motor can drive without stalling and to monitor the SG value at this load, for example some value within the range 0 to 400. The stall threshold should be a value safely within the operating limits, to allow for parameter stray.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 5 14 CoolStep Load-Adaptive Current Control CoolStep allows substantial energy savings, especially for motors which see varying loads or operate at a high duty cycle. Because a stepper motor application needs to work with a torque reserve of 30% to 50%, even a constant-load application allows significant energy savings because CoolStep automatically enables torque reserve when required.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 15 mechanical load stallGuard2 reading motor current Figure 5.2 shows the operating regions of CoolStep. The black line represents the SG measurement value, the blue line represents the mechanical load applied to the motor, and the red line represents the current into the motor coils. When the load increases, SG falls below SEMIN, and CoolStep increases the current.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 16 5.1 Tuning CoolStep Before tuning CoolStep, first tune the StallGuard2 threshold level SGT, which affects the range of the load measurement value SG. CoolStep uses SG to operate the motor near the optimum load angle of +90°. The current increment speed is specified in SEUP, and the current decrement speed is specified in SEDN. They can be tuned separately because they are triggered by different events that may need different responses.

Bits 19, 18, and sometimes 17 select the register being written, as shown in bold. The DRVCTRL register has two formats, as selected by the SDOFF bit. Bits shown as 0 must always be written as 0, and bits shown as 1 must always be written with 1. Detailed descriptions of each parameter and mode bit are given in the following sections.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 21 6.5 Driver Control Register (DRVCTRL) The format of the DRVCTRL register depends on the state of the SDOFF mode bit. SPI Mode SDOFF bit is set, the STEP/DIR interface is disabled, and DRVCTRL is the interface for specifying the currents through each coil. STEP/DIR Mode SDOFF bit is clear, the STEP/DIR interface is enabled, and DRVCTRL is a configuration register for the STEP/DIR interface. 6.5.

TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 7 29 STEP/DIR Interface The STEP and DIR inputs provide a simple, standard interface compatible with many existing motion controllers. The MicroPlyer STEP pulse interpolator brings the smooth motor operation of highresolution microstepping to applications originally designed for coarser stepping and reduces pulse bandwidth. 7.1 Timing Figure 7.1 shows the timing parameters for the STEP and DIR signals, and the table below gives their specifications.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 30 7.2 Microstep Table The internal microstep table maps the sine function from 0° to 90°, and symmetries allow mapping the sine and cosine functions from 0° to 360° with this table. The angle is encoded as a 10-bit unsigned integer MSTEP provided by the microstep counter. The size of the increment applied to the counter while microstepping through this table is controlled by the microstep resolution setting MRES in the DRVCTRL register.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 31 7.3 Changing Resolution The application may need to change the microstepping resolution to get the best performance from the motor. For example, high-resolution microstepping may be used for precision operations on a workpiece, and then fullstepping may be used for maximum torque at maximum velocity to advance to the next workpiece.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 32 In Figure 7.3, the first STEP cycle is long enough to set the STST bit. This bit is cleared on the next STEP active edge. Then, the STEP frequency increases and after one cycle at the higher rate MicroPlyer increases the interpolated microstep rate. During the last cycle at the slower rate, MicroPlyer did not generate all 16 microsteps, so there is a tiny jump in motor angle between the first and second cycles at the higher rate. 7.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 8 33 Current Setting The internal 5V supply voltage available at the pin 5VOUT is used as a reference for the coil current regulation based on the sense resistor voltage measurement. The desired maximum motor current is set by selecting an appropriate value for the sense resistor. The sense resistor voltage range can be selected by the VSENSE bit in the DRVCONF register.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 34 8.1 Sense Resistors Sense resistors should be carefully selected. The full motor current flows through the sense resistors. As they also see the switching spikes from the MOSFET bridges, a low-inductance type such as film or composition resistors is required to prevent spikes causing ringing. A compact power stage layout with massive GND plane for low-inductance and low-resistance is essential to avoid disturbance by parasitic effects.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 9 35 Chopper Operation The currents through both motor coils are controlled using choppers. The choppers work independently of each other. Figure 9.1 shows the three chopper phases: +VM +VM +VM ICOIL ICOIL ICOIL RSENSE RSENSE On Phase: current flows in direction of target current Fast Decay Phase: current flows in opposite direction of target current RSENSE Slow Decay Phase: current re-circulation Figure 9.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) Parameter TBL CHM Description Blanking time. This time needs to cover the switching event and the duration of the ringing on the sense resistor. For most low-current applications, a setting of 16 or 24 is good. For high-current applications, a setting of 36 or 54 may be required.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 37 Figure 9.2 No ledges in current wave with sufficient hysteresis (magenta: current A, yellow & blue: sense resistor voltages A and B) A too high hysteresis setting will lead to reduced chopper frequency and increased chopper noise but will not yield any benefit for the wave shape.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 38 Three parameters control SpreadCycle mode: Parameter HSTRT Description Setting Hysteresis start setting. Please remark, that this 0… 7 value is an offset to the hysteresis end value HEND. HEND Hysteresis end setting. Sets the hysteresis end 0… 2 value after a number of decrements. Decrement interval time is controlled by HDEC. The sum HSTRT+HEND must be <16. At a current setting CS of max. 30 (amplitude reduced to 240), the sum 3 is not limited.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 39 9.2 Classic Constant Off-Time Chopper The classic constant off-time chopper uses a fixed-time fast decay following each on phase. While the duration of the on phase is determined by the chopper comparator, the fast decay time needs to be fast enough for the driver to follow the falling slope of the sine wave, but it should not be so long that it causes excess motor current ripple and power dissipation.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 40 Three parameters control constant off-time mode: Parameter TFD (HSTART & HDEC0) OFFSET (HEND) NCCFD (HDEC1) Description Fast decay time setting. With CHM=1, these bits control the portion of fast decay for each chopper cycle. Sine wave offset. With CHM=1, these bits control the sine wave offset. A positive offset corrects for zero crossing error. Selects usage of the current comparator for termination of the fast decay cycle.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 41 10 Power MOSFET Stage The TMC262 provides gate drivers for two full-bridges using N- and P-channel power MOSFETs. The gate current for the MOSFETs can be adapted to influence the slew rate at the coil outputs. The main features of the stage are: - 5V gate drive voltage for low-side N-MOS transistors, 8V-10V for high-side P-MOS transistors.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 42 The duration of the complete switching event depends on the total gate charge of the MOSFETs. In Figure 10.1, the voltage transition of the gate-charge output (dotted line) takes place during the socalled Miller plateau. The Miller plateau results from the gate-to-drain capacitance of the MOSFET charging or discharging during switching.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 43 11 Diagnostics and Protection 11.1 Short Protection The TMC262 protects the MOSFET power stages against a short circuit or overload condition by monitoring the voltage drop in the high-side MOSFETs (Figure 11.1). The TMC262C also allows monitoring the voltage drop in sense resistor and low-side MOSFETs. A programmable short detection delay (shortdelay) allows adjusting the detector to work with different power stages and load conditions.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 44 The short detector is controlled by a mode bit and a parameter: Mode bit / Parameter DISS2G Description Setting Comment Short to ground detection disable bit. 0/1 0: Short to ground detection enabled 1: Short to ground detection disabled %00: 3.2µs. %01: 1.6µs. %10: 1.2µs. %11: 0.8µs.

TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 45 11.3 Temperature Sensors The TMC262 integrates a two-level temperature sensor (100°C warning and 150°C shutdown) for diagnostics and for protection of the power MOSFETs. The temperature detector can be triggered by heat accumulation on the board, for example due to missing convection cooling. Most critical situations, in which the MOSFETs could be overheated, are avoided when using the short protection.

It is designed for compatibility to existing applications, while offering a number of enhancements and options, which can be activated using the interface. Care has been taken to ensure compatibility for both devices, even if the enhanced options are switched on. ENHANCEMENTS IN TMC262C • • • • • • • More silent chopper operation, silent motor at low motor velocity.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 50 15 MOSFET Examples There are a many of N- and P-channel paired MOSFETs available suitable for the TMC232, as well as single N- and P-devices. The important considerations are the electrical data (voltage, current, RDSon), package, and configuration (single vs. dual). The following table shows a few examples of SMD MOSFET pairs for different motor voltages and currents. These MOSFETs are recent types with a low total gate charge.
TMC262 / TMC262C DATASHEET (Rev. 2.22 / 2019-FEB-22) 51 16 Layout Considerations The PCB layout is critical to good performance, because the environment includes both highsensitivity analog signals and high-current motor drive signals. A massive GND plane is required for good results, both for heat conduction as well as electrical. 16.1 Sense Resistors The sense resistors are susceptible to ground differences and ground ripple voltage, as the microstep current steps result in voltages down to 0.5mV.
