APM80905
36 V, 4 A, Low-EMI, Synchronous Buck LED Driver Module with PWM Monitor
FEATURES AND BENEFITS
• 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 solution size and cost
• Safety diagnostics for ASIL B compliance including: ▫ Low power shutdown (1 μA typical) ▫ High-side output current sense ▫ High-side MOSFET current limit protection ▫ Active-low fault flag output ▫ Unde
