IS32LT3146 Overview
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.
IS32LT3146 Key Features
