Datasheet

- production data

Features

 AEC-Q100 qualified

 Six integrated fully protected 0.09  half

bridges

 Integrated half bridges can be fully

independent or paralleled up to three in parallel

 Two levels of standby

– Standby (SPI initiated)

– Sleep (VDD=0 V)

 Very low current consumption in standby

– Only wake-up circuit active

 High level of programmability

– On-time duration

– Direction

– Current level

– Off-state fault detection

 2 external half bridge controllers (using

external N-channel MOSFETs or Smart Power

devices)

 External half bridges protected by drain source

monitoring and off-state fault detection

 2 stage charge pump for low voltage operation

 PWM current regulation up to 25 kHz

 4 MHz 24 bit SPI interface for control and

diagnostics

 Output enable for high security

 High level diagnostics

 10 bit digital current feedback (via SPI) for load

integrity check

 Thermal warning and shutdown protection

 Reverse battery protection using an external 

N-Ch MOSFET.

 TQFP64L exposed pad package

Application

The L99UDL01 is designed for use in a central

door lock system driving all of the door lock

actuators. This device is able to adapt to most

central door lock configurations.

Description

The L99UDL01 is a multiple half-bridge IC with 6

integrated outputs that are PWM configurable and

current regulated and up to two externally

configured half bridges for higher current nodes.

The level of diagnostics includes open load, short

to battery, short to ground, and load integrity via

10 bit current feedback.

The L99UDL01 is commanded entirely by SPI

using duration and current level commands.
