BTS5045-2EKA Power Stage 5 Power Stage The power stages are built using an N-channel vertical power MOSFET (DMOS) with charge pump. 5.1 Output ON-state Resistance The ON-state resistance RDS(ON) depends on the supply voltage as well as the junction temperature TJ. Figure 8 shows the dependencies in terms of temperature and supply voltage for the typical ON-state resistance. The behavior in reverse polarity is described in Chapter 6.4.
PAGE 16
BTS5045-2EKA Power Stage 5.3 Inductive Load 5.3.1 Output Clamping When switching OFF inductive loads with high side switches, the voltage VOUT drops below ground potential, because the inductance intends to continue driving the current. To prevent the destruction of the device by avalanche due to high voltages, there is a voltage clamp mechanism ZDS(AZ) implemented that limits negative output voltage to a certain level (VS - VDS(AZ)). Please refer to Figure 10 and Figure 11 for details.

BTS5045-2EKA Power Stage 5.3.2 Maximum Load Inductance During demagnetization of inductive loads, energy has to be dissipated in the BTS5045-2EKA. This energy can be calculated with following equation: V S – V DS ( AZ ) RL × IL ⎞ L E = V DS ( AZ ) × ------ × -------------------------------× ln ⎛ 1 – -------------------------------+ IL ⎝ RL RL V S – V DS ( AZ )⎠ (1) Following equation simplifies under the assumption of RL = 0 Ω.

BTS5045-2EKA Protection Functions 6 Protection Functions The device provides integrated protection functions. These functions are designed to prevent the destruction of the IC from fault conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are designed for neither continuous nor repetitive operation. 6.

BTS5045-2EKA Protection Functions VOUT undervoltage behavior .vsd VS(UV) Figure 15 Undervoltage Behavior 6.3 Overvoltage Protection VS(OP) VS There is an integrated clamp mechanism for overvoltage protection (ZD(AZ)). To guarantee this mechanism operates properly in the application, the current in the Zener diode has to be limited by a ground resistor. Figure 16 shows a typical application to withstand overvoltage issues.
PAGE 23
BTS5045-2EKA Protection Functions 6.4 Reverse Polarity Protection In case of reverse polarity, the intrinsic body diodes of the power DMOS causes power dissipation. The current in this intrinsic body diode is limited by the load itself. Additionally, the current into the ground path and the logic pins has to be limited to the maximum current described in Chapter 4.1 with an external resistor. Figure 17 shows a typical application.

BTS5045-2EKA Diagnostic Functions 7 Diagnostic Functions For diagnosis purpose, the BTS5045-2EKA provides a combination of digital and analog signals at pin IS. These signals are called SENSE. In case the diagnostic is disabled via DEN, pin IS becomes high impedance. In case DEN is activated, the SENSE of the channel X is enabled/disabled via associated pin DSEL. Table 7 gives the truth table.

PAGE 29
BTS5045-2EKA Diagnostic Functions 7.3 SENSE Signal in the Nominal Current Range Figure 21 and Figure 22 show the current sense as a function of the load current in the power DMOS. Usually, a pull-down resistor RIS is connected to the IS pin. This resistor has to be higher than 560 Ω to limit the power losses in the sense circuitry. A typical value is 1.2 kΩ. The blue curve represents the ideal SENSE, assuming an ideal kILIS factor value.

PAGE 31
BTS5045-2EKA Diagnostic Functions 7.3.3 SENSE Signal in Open Load 7.3.3.1 Open Load in ON Diagnostic If the channel is ON, a leakage current can still flow through an open load, for example due to humidity. The parameter IL(OL) gives the threshold of recognition for this leakage current. If the current IL flowing out the power DMOS is below this value, the device recognizes a failure, if the DEN (and DSEL) is selected. In that case, the SENSE current is below IIS(OL).

BTS5045-2EKA Diagnostic Functions 7.3.4 SENSE Signal with OUT in Short Circuit to VS In case of a short circuit between the OUTput-pin and the VS pin, all or portion (depending on the short circuit impedance) of the load current will flow through the short circuit. As a result, a lower current compared to the normal operation will flow through the DMOS of the BTS5045-2EKA, which can be recognized at the SENSE signal.
