Description
The VND5160AJ-E is a monolithic device made
using STMicroelectronics VIPower 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.
