DESCRIPTION

The VN750, VN750S, VN750-B5 are a monolithic device designed in STMicroelectronics VIPower Technology, intended for driving any kind of load with one side connected to ground. Active V

pin voltage clamp protects the device

CC

against low energy spikes (see ISO7637 transient compatibility table). Active current limitation

/ VN750S / VN750-B5

HIGH SIDE DRIVER

SO-8

ORDER CODES :

PENTAWATT SO-8 P2PAK

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 VCCis detected in

the off state.Device automatically turns off in case of ground pin disconnection.
