... Input Circuit Figure 7 shows the input circuit of the BTS 3256D. It’s ensured that the device switches off in case of open input pin. A Zener structure protects the input circuit against ESD pulses. As the BTS 3256D 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 Diagnosis Fault Information” ...
