Analog Devices Inc. MAX25613 Automotive IR LED Controllers
Analog Devices Inc. MAX25613 Automotive Infrared (IR) LED Controllers are single-channel, high-current LED drivers for automotive Driver Monitoring Systems (DMS). These LED controllers operate from 5V to 48V input voltage range and can drive a string of LEDs with a maximum output voltage of 55V. The MAX25613 LEDs operate to achieve high LED drive capability while minimizing the peak current on the battery harness. These automotive LED controllers sense output current at the high side of the LED string. The MAX25613 controllers include a fault flag that indicates LED short to battery, LED short to ground, LED open, and thermal shutdown.
The MAX25613 controllers also include built-in spread-spectrum modulation for improved electromagnetic compatibility performance. These IR LED controllers operate within a -40°C to +125°C automotive temperature range. These LED controllers come in a space-saving 4mm x 4mm 20-pin side-wettable TQFN or a 20-pin TSSOP package. Applications include driver monitoring systems and IR LED drivers.
