REVERSE BATTERY PROTECTION (**)
combined with thermal shutdown and automatic
restart protects the device against overload. The
device detects open load condition both in 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.
DESCRIPTION
The VND810 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
