The device is a double channel high-side driver
manufactured using ST proprietary VIPower®
M0‑ 7 technology and housed in PowerSSO-36
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.
AEC-Q100 qualified
General
Double channel smart high-side driver
with MultiSense analog feedback
Very low standby current
Compatible with 3 V and 5 V CMOS
outputs
MultiSense diagnostic functions
Multiplexed analog feedback of: load
current with high precision proportional
current mirror, VCC supply voltage and
TCHIP device temperature
Overload and short to ground (power
limitation) indication
Thermal shutdown indication
OFF-state open-load detection
Output short to VCC detection
Sense enable/disable
Protections
Undervoltage shutdown
Overvoltage clamp
Load current limitation
Self limiting of fast thermal transients
June 2017
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 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 VCC 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.
