Additional Infomation About Product

IS32LT3181 RCL DUAL INTENSITY, SIX CHANNEL LED DRIVER WITH FAULT DETECTION April 2017 GENERAL DESCRIPTION FEATURES The IS32LT3181 is a six channel linear current Operating voltage from 6V to 42VDC regulator for automotive rear tail light applications such - Withstand 50V load dump as RCL (Rear Combination Lamps) and CHMSL 6 constant-current channel sinks (Center High Mounted Stop Lamps). It is fully - Adjustable from 10mA to 75mA per channel programmable with two LED brightness levels for the - Channel paralleling for higher current different intensity requirements of stop bright (DC - Low dropout voltage of 0.8V 35mA mode) and tail dim (PWM mode). - Slew rate control on each output for better EMI A logic level at the PWM pin is used to select between performance the tail and stop output conditions. The stop condition Integrated PWM dimming engine provides two provides the highest intensity output, while the tail LED brightness levels without external logic condition utilizes an internally generated PWM signal - Tail duty cycle programmable from 1% to 95% to reduce the intensity of the LEDs light output. - PWM logic level input selects between full brightness and PWM dimming levels An active low fault output signal reports a device error Support for optional FET to minimize device power condition. The FAULTB pin of several devices can be consumption tied together to disable all the output stages when a fault is detected by any one of the devices. Open Drain FAULTB reporting pin - Programmable FAULTB delay time The sink current at the OUTx pins is easily set with a - Programmable UVLO threshold single resistor at the STOP pin. The constant-current - LED open circuit detection sink outputs can be combined in parallel to create - STOP pin over current protection higher current-driving capability on a single string. A - Over temperature protection second resistor at the TAIL pin sets the duty cycle of Device disable upon fault detection the internal PWM oscillator for dimming the LED output when operating in the tail condition. - Parallel connection to other devices AEC-Q100 qualification An external FET (optional) can be implemented for operation with wide varying supply voltages to APPLICATIONS minimize device thermal dissipation. Rear Combinational Lamp (RCL) The IS32LT3181 is offered in an eTSSOP-16 package.
