DESCRIPTION

The VND920 is a double chip device made by

using

STMicroelectronics

VIPower

M0-3

Technology, intended for driving any kind of load

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. Built-

in analog current sense output delivers a current

proportional

to

the

load

current.

Device

automatically turns off in case of ground pin

disconnection.
