Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). Active current limitation BLOCK DIAGRAM combined with thermal shutdown and automatic restart protect the device against overload. The device detects open load condition both is on and off state. Output shorted to VCC is detected in the off state. Device automatically turns off in case of ground pin disconnection.

This can be used with any type of load. The following is an indication on how to dimension the RGND resistor. 1) RGND ≤ 600mV / (IS(on)max). 2) RGND ≥ (−VCC) / (-IGND) where -IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the of the device’s datasheet.
