Description
SO-16L
The VN920 is a monolithic device designed in STMicroelectronics VIPower M0-3 technology. The VN920 is intended for driving any type of load with one side connected to ground. The active V
pin voltage clamp protects the device against
CC
low energy spikes (see ISO7637 transient compatibility table). Active current limitation combined with thermal shutdown and automatic restart protects the device against over-load.
The device integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns off in the case where the ground pin becomes disconnected.

This small signal diode can be safely shared amongst several different HSDs. Also in this case, the presence of the ground network will produce a shift (600mV) in the input threshold and in the status output values if the microprocessor ground is not common to the device ground. This shift will not vary if more than one HSD shares the same diode/resistor network.
Series resistor in INPUT and STATUS lines are also required to prevent that, during battery voltage transient, the current exceeds the absolute maximum rating.
Safest configuration for unused INPUT and STATUS pin is to leave them unconnected.

3.2 Load dump protection

Dld is necessary (Voltage Transient Suppressor) if the load dump peak voltage exceeds the V
max DC rating. The same applies if the device is subject to transients on the VCC line

that are greater than the ones shown in the ISO 7637-2: 2004(E) table.

3.3 MCU I/Os protection
