Description
The devices are single channel high-side drivers
manufactured using ST proprietary VIPower
®
M0-7 technology and housed in PowerSSO-16
and SO-8 packages. The devices are 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 devices integrate 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 dedicated multifunction multiplexed analog
output pin delivers sophisticated diagnostic
functions including high precision proportional
load current sense, supply voltage feedback and
chip temperature sense, in addition to the
detection of overload and short circuit to ground,
short to V
CC
and OFF-state open-load.
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.
