特性 Features

? AEC-Q100 qualified

? Extreme low voltage operation for deep cold cranking applications (compliant

with LV124, revision 2013)

? General

– Quad channel smart high-side driver with current sense analog feedback

– Very low standby current

– Compatible with 3 V and 5 V CMOS outputs

? CurrentSense diagnostic functions

– 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 (with external pull-up)

– Output short to VCC detection

– Sense enable/disable

? Protections

– Undervoltage shutdown

– Overvoltage clamp

– Load current limitation

– Self limiting of fast thermal transients

– Configurable latch-off on overtemperature or power limitation with

dedicated fault reset pin

– Loss of ground and loss of VCC

– Reverse battery with external components

– Electrostatic discharge protection

Applications

? Automotive resistive, inductive and capacitive loads
