IS32FL3202 LED Controller

Lumissil’s three-channel smart LED driver with CAN bus is ideal for dynamic automotive interior RGB lighting

Image of Lumissil's IS32FL3202 LED ControllerLumissil’s IS32FL3202 smart LED driver significantly increases the number of addressable RGB LEDs within a single communication channel, facilitating dynamic color and intensity changes across hundreds of RGB LEDs. This controller enables lighting engineers to innovate automotive cabin lighting applications, including decorative trim, roof starlight, and integrated seat and door RGB lighting.

Each of the IS32FL3202’s three channels supports 6-bit current adjustment for color setting and 12-bit PWM for smooth LED dimming control. To minimize EMI, the IS32FL3202 supports a spread spectrum on the PWM clock generator. Additionally, it supports location address assignment (LAA) for addressing hundreds of RGB LEDs without the need for address pins. The maximum output current of each LED channel is 63 mA.

The IS32FL3202 incorporates a state machine core that enables low-latency communication with any microcontroller over a CAN bus interface, speeding up the transmission of instructions for individual LED brightness and color control. This integrated state machine also measures the RGB LED temperature and employs a built-in temperature compensation algorithm to ensure consistent luminance across a wide temperature range. The temperature-compensated PWM data is stored in 16-bit registers. All the IS32FL3202 registers can be accessed and updated via the fast CAN bus.
