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, and to provide protection
and diagnostics.
The device integrates advanced protective
functions such as load current limitation, overload
active management by power limitation and
overtemperature shutdown.
A combination of INPUT and FR_DIAG pins
latches the output in case of fault, disables the
latch-off functionality and enables OFF-state
diagnostic.
