Description
The device is a quad channel high-side driver
manufactured using ST proprietary VIPower®
technology and housed in PowerSSO-16
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 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

Function
Battery connection.
Power output.
Ground connection. Must be reverse battery protected by an external
diode / resistor network.
Voltage controlled input pin with hysteresis, compatible with 3 V and 5 V
CMOS outputs. It controls output switch state.
Multiplexed analog sense output pin; it delivers a current proportional to
the selected diagnostic: load current, supply voltage or chip temperature.
Active high compatible with 3 V and 5 V CMOS outputs pin; it enables
the MultiSense diagnostic pin.
Active high compatible with 3 V and 5 V CMOS outputs pin; they address
the MultiSense multiplexer.
Active low compatible with 3 V and 5 V CMOS outputs pin; it unlatches
the output in case of fault; If kept low, sets the outputs in auto-restart
mode.
