Description
The VND5T050AK-E is a monolithic device made
using STMicroelectronics
®
VIPower
®
technology,
intended for driving resistive or inductive loads
with one side connected to ground. Active V
CC
pin
voltage clamp protects the device against low
energy spikes.
This device integrates an analog current sense
which delivers a current proportional to the load
current.
Fault conditions such as overload,
overtemperature or short to V
CC
are reported via
the current sense pin.
Output current limitation protects the device in
overload condition. The device will latch off in
case of overload or thermal shutdown.
The device is reset by a low level pass on the fault
reset standby pin.
A permanent low level on the inputs and fault
reset standby pin disable all outputs and set the
device in standby mode.
