IS32LT3180 - ISSI

IS32LT3180 LINEAR CURRENT DRIVER

The IS32LT3180 is an eight channel linear current regulator for automotive rear tail light applications such as RCL (Rear Combination Lamps) and CHMSL (Center High Mounted Stop Lamps). It is fully programmable with two LED brightness levels for the different intensity requirements of “stop” bright (DC mode) and “tail” dim (PWM mode). A logic level at the PWM.

Features
