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

pin voltage clamp protects the device

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

is detected in the

off-state. Device automatically turns off in case of

ground pin disconnection.

VN750PS-E Electrical specifications 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. 2.
