APM80905
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 ply 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 solution size and cost
- Robust protection against: ▫ Adjacent pin-to-pin short ▫ Pin-to-ground short ▫ ponent open/short faults
Applications
- Driver monitoring systems
