MAX25614 Automotive IR LED/VCSEL Drivers

Analog Devices MAX25614 Automotive IR LED/VCSEL Drivers are high-current IR LED/VCSEL for automotive driver monitoring systems (DMS). The ICs drive IR LED/VCSEL strings of up to 35V from a 4.5V to 36V input supply. The MAX25614 can drive up to the 10A peak current to the IR emitter. It's designed for applications where the IR emitter is pulsed on and off, typically at 60Hz or the shutter speed of the corresponding image sensor. The Analog Devices MAX25614A/MAX25614B uses fixed-frequency, average current-mode control with programmable switching frequency options of 420kHz, 1MHz, 1.6MHz, and 2.1MHz. Both an inrush current-limiting pFET and a low-side switching nFET are integrated.
