High Voltage, Reverse Polarity and Short Circuit Protection

The ZSC31150 is designed for 5V power supply operation.

The ZSC31150 and the connected sensor are protected from overvoltage and reverse polarity damage by an

internal supply voltage limiter. The analog output AOUT can be connected (short circuit, overvoltage and

reverse) with all potentials in protection range under all potential conditions at the pins VDDE and VSSE.

All external components – explained in application circuit in chapter 3 – are required to guarantee this

operation. The protection is no time limited. Refer 'ZSC31150 High Voltage Protection Description' for a

detailed description of protection cases and conditions.
