Description
The device is a quad channel high-side driver
manufactured using the latest ST proprietary
VIPower® technology and housed in a
PowerSSO-36 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.
AEC-Q100 qualified
General
Quad channel smart high-side driver
with MultiSense analog feedback
LED Mode for channel 0 and 1
Very low standby current
Compatible with 3 V and 5 V CMOS
outputs
The device integrates advanced protective
functions such as load current limitation, overload
active management by power limitation and
overtemperature shutdown with configurable
latch-off.
MultiSense diagnostic functions
Multiplexed analog feedback of:
Load current with high precision
proportional current mirror;
VCC supply voltage;
TCHIP device temperature
Overload and short to ground (power
limitation) indication
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 such as 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 VCC
and OFF-state open-load.
Thermal shutdown indication
OFF-state open load detection
Output short to VCC detection
Sense enable/disable
Protections
Undervoltage shutdown
Overvoltage clamp
The device features a dedicated LED Mode.
