DESCRIPTION
The VND5012AK-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.
