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
CC
pin voltage clamp protects the device
against low energy spikes (see ISO7637 transient
compatibility table). Active current limitation
BLOCK DIAGRAM
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 V
CC
is detected in
the off state. Device automatically turns off in case
of ground pin disconnection.
