Description
The VND5050AJ-E, VND5050AK-E is a monolithic
device made using STMicroelectronics VIPower
M0-5 technology. It is 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 (see ISO7637
transient compatibility table).
This device integrates an analog current sense
which delivers a current proportional to the load
current (according to a known ratio) when
CS_DIS is driven low or left open.
When CS_DIS is driven high, the CURRENT
SENSE pin is in a high impedance condition.
Output current limitation protects the device in
overload condition. In case of long overload
duration, the device limits the dissipated power to
safe level up to thermal shut-down intervention.
Thermal shut-down with automatic restart allows
the device to recover normal operation as soon as
fault condition disappears..
