GENERAL DESCRIPTION
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).

FEATURES
● Output current programmable from 10mA to
   75mA
● Tail duty cycle programmable from 1% to 95%
● Linear voltage regulator to optimize consumption
   on device
● Low dropout voltage of 0.8V@35mA
● Slew rate control on each output for better EMI
   performance
● PWM logic level input selects between full
   brightness and PWM dimming levels
● FAULT reporting
● LED open/short circuit detection
● Input overvoltage protection
● STOP pin overcurrent protection
● Thermal rollback of output current
● Withstand 50V load dump
● AEC-Q100 qualification (pending)

APPLICATIONS
● Rear Combinational Lamp (RCL)
● Center High Mount Stop Light (CHMSL)
● Daytime running lamp
● Fog lamps
● Turn signal
