DESCRIPTION
The VN750SM 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
CC
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 protect the device against overload.
The device detects open load condition both in on
and off state. The openload threshold is aimed at

detecting the 5W/12V standard bulb as an
openload fault in the on state. Output shorted to
V
CC
is detected in the off state. Device
automatically turns off in case of ground pin
disconnection.
