DESCRIPTION

The DRV8805 provides an integrated solution for driving unipolar stepper motors. It includes four low side drivers

with overcurrent protection and provides built-in diodes to clamp turn-off transients generated by the motor

windings.

Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated. Three

stepping modes are supported: 2 phase (full-step), 1-2 phase (half-step), and 1-phase (wave drive).

In the SOIC (DW) package, the DRV8805 can supply up to 1.5-A (one channel on) or 800-mA (all channels on)

continuous output current per channel, at 25°C. In the HTSSOP (PWP) package, it can supply up to 2-A (one

channel on) or 1-A (four channels on) continuous output current per channel, at 25°C with proper PCB

heatsinking.

Internal shutdown functions are provided for over current protection, short circuit protection, under voltage

lockout and overtemperature and faults are indicated by a fault output pin.

The DRV8805 is available in a 20-pin thermally-enhanced SOIC package and a 16-pin HTSSOP package (Eco-

friendly: RoHS & no Sb/Br).

DRV8805 www.ti.com SLVSAW3C – JULY 2011 – REVISED MARCH 2012 FUNCTIONAL DESCRIPTION Output Drivers The DRV8805 contains four protected low-side drivers. Each output has an integrated clamp diode connected to a common pin, VCLAMP. VCLAMP can be connected to the main power supply voltage, VM. It can also be connected to a zener or TVS diode to VM, allowing the switch voltage to exceed the main supply voltage VM.

DRV8805 www.ti.com SLVSAW3C – JULY 2011 – REVISED MARCH 2012 nENBL and RESET Operation The nENBL pin enables or disables the output drivers. nENBL must be low to enable the outputs. nENBL does not affect the operation of the serial interface logic. Note that nENBL has an internal pulldown. The RESET pin, when driven active high, resets the internal logic. The indexer is reset to the home state. All inputs are ignored while RESET is active. Note that RESET has an internal pulldown.

DRV8805 SLVSAW3C – JULY 2011 – REVISED MARCH 2012 www.ti.com THERMAL INFORMATION Thermal Protection The DRV8805 has thermal shutdown (TSD) as described above. If the die temperature exceeds approximately 150°C, the device will be disabled until the temperature drops to a safe level. Any tendency of the device to enter TSD is an indication of either excessive power dissipation, insufficient heatsinking, or too high an ambient temperature.
