The IS32LT3137 is a linear programmable current regulator consisting of 12 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 multip.
spread spectrum on the internal PWM and LED channel outputs have programmable slew rate control and phase delay to mitigate EMI and power supply inrush current.
The IS32LT3137 is targeted at the automotive market such as interior accent lighting and exterior tail lighting. It is offered in WFQFN-32 (5mm×5mm) package.
