Description
The device is a quad channel high-side driver
manufactured using ST proprietary VIPower®
M0-7 technology and housed in PowerSSO-16
package. The device is designed to drive 12 V
automotive grounded loads through a 3 V and 5
V CMOS-compatible interface, providing
protection and diagnostics.
The device integrates advanced protective
functions such as load current limitation, overload
active management by power limitation and
overtemperature shutdown with configurable
latch-off.
A FaultRST pin unlatches the output in case of
fault or disables the latch-off functionality.
A sense enable pin allows OFF-state diagnosis to
be disabled during the module low-power mode
as well as external sense resistor sharing among
similar devices.
