IS32LT3146 - STANDALONE 6-CHANNEL LINEAR LED DRIVER

Datasheet Summary

Description

The IS32LT3146 device is a six-channel linear LED driver with a power resistor to shunt the power dissipation to optimize the thermal stress on the device.

It supports both sequential turn on mode and traditional blink mode for turn signal light application.

Features

Wide input voltage range: 5V~40V.
Thermal shunt resistor to optimize the device thermal stress.
Programmable sequential turn on of each channel - ±5% timer accuracy - Timing programmable by external resistors - Stand-alone sequential turn on timing for multiple devices operation (no signal wire connection among the devices) - Synchronized sequential turn on timing for multiple devices operation - Sequential turn on style selectable: one by one, two by two, three by th.

IS32LT3146 40V/450mA, STANDALONE 6-CHANNEL LINEAR LED DRIVER WITH THERMAL SHUNT May 2024 GENERAL DESCRIPTION The IS32LT3146 device is a six-channel linear LED driver with a power resistor to shunt the power dissipation to optimize the thermal stress on the device. It supports both sequential turn on mode and traditional blink mode for turn signal light application. A logic level at the SEQEN pin is used to switch between these two modes. The startup delay time and channel to channel internal delay time of the sequential turn on are fully programmable by external resistors, and microcontroller is not required. The sequential turn on mode is able to implement multiple devices synchronization operation to realize more than 6 LED strings sequential turn on.
