Features and Benefits
- Buck/Buck-Boost Maxim Proprietary Control Architecture
- Analog Dimming Control
The MAX25613B evaluation kit is a buck-boost, highcurrent IR LED driver for automotive driver monitoring systems (DMS). It can take an input voltage from 7V to 18V and can drive a string of LEDs with a maximum output voltage of 2V to 12V. The EV kit operates using a Maxim proprietary architecture to achieve high LED drive capability while minimizing the peak current on the battery harness. The EV kit 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 controls the LED on/off, and the ICTRL input provides additional analog dimming capability in the device. It also includes a fault flag that indicates LED short to battery, LED short to ground, LED open, and thermal shutdown. It has built-in spread-spectrum modulation for improved electromagnetic compatibility performance. The EV kit comes with the MAX25613BATP/VY+ installed, which is functionally and pin compatible with the MAX25613ATP/VY+, but with improved minimum on-time of the DL gate driver.
