Manufacturing Trending products to spec [Best of 2016] LED driver for auto interior lighting Manufacturing Group December 28, 2016 1 min The IS32LT3175 linear LED driver enables reduced bill of material count for low-cost and compact designs. Integrating a single channel LED driver with a programmable 150mA current source, push-button control, signal input, and integrated programmable fade-in/fade-out lighting control, it is designed for use in LED-based map lights, dome lights, and door lights. The driver integrates all functions, eliminating the need for a micro-controller and several discrete components, and only individual resistors are needed to adjust the LED current from 10mA to 150mA as well as the fade up/down ramp speed. The driver can be controlled by a momentary contact switch or a courtesy signal input. An integrated debounce and latch circuit conditions the switch input, so a single press of the mechanical switch does not appear as multiple presses.
