MAX16835ATE+T

LED Driver IC Overview

The MAX16835ATE+T is a high-voltage linear LED driver IC designed for automotive and industrial applications. It operates from an input voltage range of 6.5V to 40V, delivering up to 350mA of output current to one or more strings of high-brightness LEDs. The device features ±3.5% output current accuracy and includes an integrated pass element with a typical low-dropout voltage of 0.55V. It supports PWM dimming via a high-voltage enable pin and provides thermal shutdown and short-circuit protection. The component is housed in a thermally enhanced 5mm x 5mm 16-pin TQFN package and is specified over the -40°C to +125°C temperature range.
