Description

0.5 µA

The device is a double channel high-side driver

manufactured using ST proprietary VIPower^®

technology and housed in PowerSSO-12

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.

•

Automotive qualified

Extreme low voltage operation for deep cold

cranking applications (compliant with LV124,

revision 2013)

•

General

−

Double channel smart high-side driver

with CurrentSense analog feedback

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.

−

•

CurrentSense diagnostic functions

A current sense delivers high precision

proportional load current sense in addition to the

detection of overload and short circuit to ground,

short to V_CCand off-state open-load.

−

Multiplexed analog feedback of: load

current with high precision proportional

current mirror

−

Overload and short to ground (power

limitation) indication

Thermal shutdown indication

Off-state open-load detection

Output short to V_CCdetection

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.
