Description
The device is a double channel high-side driver
manufactured using STMicroelectronics
proprietary VIPower® M0-5 technology. It is
intended for driving resistive or inductive loads
with one side connected to ground.
Active VCC pin voltage clamp and load dump
protection circuit protect the device against
transients on the VCC pin. The 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 high impedance.
Output current limitation protects the device in
overload condition. In case of long duration
overload, the device limits the dissipated power to
a safe level up to thermal shutdown intervention.
Thermal shutdown with automatic restart allows
the device to recover normal operation as soon as
a fault condition disappears.
