Description

Standby current (max)

0.5 µA

The device is a double channel high-side driver

manufactured using ST proprietary VIPower^®

M0-7 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.



AEC-Q100 qualified

General



Double channel smart high-side driver

with MultiSense analog feedback

Very low standby current



The device integrates advanced protective

functions such as load current limitation, overload

active management by power limitation and

overtemperature shutdown with configurable

latch-off.

Compatible with 3 V and 5 V CMOS

outputs



MultiSense diagnostic functions



Multiplexed analog feedback of: load

current with high precision proportional

current mirror, V_CCsupply voltage and

T_CHIPdevice temperature

A FaultRST pin unlatches the output in case of

fault or disables the latch-off functionality.



Overload and short to ground (power

limitation) indication

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_CCand OFF-state open-load.



Thermal shutdown indication

OFF-state open-load detection

Output short to V_CCdetection

Sense enable/disable



Protections



Undervoltage shutdown

Overvoltage clamp

Load current limitation

Self limiting of fast thermal transients

Configurable latch-off on

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.
