resistive and inductive actuators.
Description
The device is a single channel high-side driver
manufactured using ST proprietary VIPower®
technology and housed in the Octapak 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.
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.
