IS32LT3129A - TRIPLE CHANNEL LINEAR LED DRIVER

Datasheet Summary

Description

The IS32LT3129A is a programmable triple channel linear current regulator; two channels of up to 150mA each for LED lighting and a single channel of up to 30mA for illuminating switches.

Features

  • Operating voltage range, 5V to 42V.
  • 1MHz I2C-compatible interface.
  • Dual channel current sources - Individual programmable current via a single external resistor and I2C - Configurable from 20mA to 150mA.
  • Single channel 30mA (Max. ) current source for switch illumination.
  • EN input supports either momentary contact or latched switch - Input is debounced and latched - Lower priority than I2C input - Gamma corrected Fade ON/OFF algorithm - Pull down resis.

IS32LT3129A TRIPLE CHANNEL LINEAR LED DRIVER WITH I2C INTERFACE AND FADE ON/OFF GENERAL DESCRIPTION The IS32LT3129A is a programmable triple channel linear current regulator; two channels of up to 150mA each for LED lighting and a single channel of up to 30mA for illuminating switches. The device operates as a fully configurable theatrical dimming LED driver; External resistors will program the current levels as well as the LED fade ON/OFF ramp rate. In additional, the I2C interface supports writing/reading function for MCU to select switch type (momentary contact or latched), individually configure the output current levels and fade on/off ramp rate, or get the state of device and the fault flag of open/short circuit and thermal shutdown.
