IS32LT3131C Overview
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...
