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...
