The MAX25613 is a single-channel, high-current IR LED driver for automotive Driver Monitoring Systems (DMS). It can take an input voltage from 5V to 48V and can drive a string of LEDs with a maximum output voltage of 55V. The MAX25613 operates using a Maxim proprietary, dual-control architecture to achieve high LED drive capability while minimizing the peak current on the battery harness.The MAX25613 senses output current at the high side of the LED string. High-side current sensing is required to protect against shorts from the output to the ground or battery input. The PWM input provides LED dimming ratios of up to 5000:1, and the ICTRL input provides additional analog dimming capability in the device. The MAX25613 also includes a fault flag that indicates LED short to battery, LED short to ground, LED open, and thermal shutdown. The MAX25613 has built-in spread-spectrum modulation for improved electromagnetic compatibility performance. The MAX25613 is available in a space-saving (4mm x 4mm) 20-pin side-wettable TQFN or a-20 pin TSSOP package, and is specified to operate over the -40°C to +125°C automotive temperature rangeApplicationsDriver Monitoring SystemsIR LED drivers
