pin. A zener structure protects the input circuit against ESD pulses. As the BTS3160D has a supply pin, the
operation of the power MOS can be maintained regardless of the voltage on the IN pin, therefore a digital status
feedback down to logic low is realized. For readout of the fault information, please refer to

Figure 7
5.2.1
The BTS3160D provides digital status information via an increased current on the IN / Fault pin.
The voltage on this pin is pulled down to logic low if a proper resistor is used. An example for the required circuitry
is shown in
The increased current I
voltage at the IN/Fault pin will decrease. The voltage at the pin is determined by the current and the serial resistor.
We recommend 3k3 for a 3.3V µC and 5k6 for a 5V µC to achieve a logic low signal.
