APM80905 Datasheet - Allegro

APM80905 Synchronous Buck LED Driver Module

The APM80905 is a 36 V, 4 A, ASIL B, low-EMI, synchronous buck switching regulator module that provides a regulated current output to drive high-power infrared or standard LEDs. The module integrates both the high-side and low-side N-channel MOSFET switches, high-frequency input voltage and boot cap.

APM80905 Features

* Automotive ASIL B, AEC-Q100 qualified solution for infrared LED driver monitoring system (DMS)

* Ultra-low EMI architecture with integrated EMImitigation capacitors and spread spectrum operation to comply with automotive requirements

* Safety protection against out-of-range
