IS32LT3131B - 12-CHANNEL LINEAR LED DRIVER

This page provides the datasheet information for the IS32LT3131B, a member of the IS32LT3131A 12-CHANNEL LINEAR LED DRIVER family.

Datasheet Summary

Description

The IS32LT3131A/B/C is a linear LED driver with 12 programmable current sources capable of up to 75mA each.

It supports an external thermal shunt resistor that dissipates thermal energy away from the LED driver to minimize thermal stress on the device and maintain a high output current accuracy.

Features

  • Wide input voltage supply from 4.5V to 40V.
  • Thermal shunt resistor to minimize device thermal stress.
  • UART interface (IS32LT3131A),.

IS32LT3131A/B/C 12 CHANNEL LINEAR LED DRIVER WITH UART/CANLITE/SPI INTERFACE May 2024 1 GENERAL DESCRIPTION The IS32LT3131A/B/C is a linear LED driver with 12 programmable current sources capable of up to 75mA each. It supports an external thermal shunt resistor that dissipates thermal energy away from the LED driver to minimize thermal stress on the device and maintain a high output current accuracy. There are three bus interface options, UART (IS32LT3131A), CANLITE (IS32LT3131B) or SPI (IS32LT3131C) used for individual output control by a host MCU. A configurable watchdog automatically sets fail-safe modes should the bus interface loose communication. Each output can individually support 10-bit PWM dimming and 8-bit DC current adjustment.
