APM80905 - Synchronous Buck LED Driver Module

General Description

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.

Key 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 PWM on-time and duty cycle with PWM monitoring feature for eye-safe operation.
  • High integration architecture including high-side and low-side MOSFET switches and 5 V peripheral LDO to reduce.
