IS32LT3180 Overview
The IS32LT3180 is an eight channel linear current regulator for automotive rear tail light applications such as RCL (Rear bination 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 pin is used to select between the tail and stop output...
