Description
The VN750PS-E is a monolithic device designed
in STMicroelectronics™ VIPower™ M0-3
Technology intended for driving any kind of load
with one side connected to ground.
Active V
against low energy spikes (see ISO7637 transient
compatibility table). Active current limitation
combined with thermal shutdown and automatic
restart help protect the device against overload.
The device detects open load condition in on and
off-state. Output shorted to V
off-state. Device automatically turns off in case of
ground pin disconnection.

Stress values that exceed those listed in the “Absolute maximum ratings” table can cause
permanent damage to the device. These are stress ratings only and operation of the device
at these or any other conditions greater than those indicated in the operating sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability. Refer also to the STMicroelectronics sure program and
other relevant quality documents.

1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals
must be used together with a proper software strategy. If the device operates under abnormal conditions this software must
limit the duration and number of activation cycles.
