L99UDL01 L99UDL01 Automotive Universal Door Lock IC Datasheet - production data 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 TQFP64L 10x10 Application The L99UDL01 is designed for use in a central Features door lock system driving all of the door lock actuators. This device is able to adapt to most AEC-Q100 qualified central door lock configurations. Six integrated fully protected 0.09 half bridges Description Integrated half bridges can be fully independent or paralleled up to three in parallel The L99UDL01 is a multiple half-bridge IC with 6 integrated outputs that are PWM configurable and Two levels of standby current regulated and up to two externally Standby (SPI initiated) configured half bridges for higher current nodes. Sleep (VDD=0 V) The level of diagnostics includes open load, short Very low current consumption in standby to battery, short to ground, and load integrity via 10 bit current feedback. Only wake-up circuit active High level of programmability The L99UDL01 is commanded entirely by SPI using duration and current level commands. On-time duration Direction Table 1.
