IS32LT3138 18 CHANNELS, LINEAR LED DRIVER WITH UART INTERFACE May 2024 1 GENERAL DESCRIPTION The IS32LT3138 is a linear programmable current regulator consisting of 18 output channels capable of up to 100mA each. It has a UART interface compatible with CANFD PHY for communication with a master microcontroller or ECU. It uses a command and response protocol mastered by the host microcontroller to read and write the registers to and from one or multiple IS32LT3138 devices. Each output can individually support 12-bit PWM dimming and 7-bit DC current adjustment. The outputs can be combined to provide higher current drive capability to max 1.8A.
