Lumissil IS32FL3265 LED Drivers

Lumissil IS32FL3265 LED Drivers are designed with 18 high voltage (40V) constant current 8-bits Pulse Width Modulated (PWM) channels for smooth LED brightness control. These LED drivers provide an 8-bit output current control register on each channel that allows fine-tuning of the channel current for rich RGB color mixing. The IS32FL3265 LED drivers offer programmable H/L logic, accurate color rendition, clock IO pin for multi-chip synchronization, and thermal roll-off programmable set point. These LED drivers can be configured to a minimum current consumption mode by either pulling the SDB pin low or by using the software shutdown feature.

The IS32FL3265A LED driver features 1MHz I2C with automatic address increment and the SDB rising edge resets the I2C interface. The IS32FL3265B LED driver features 12MHz SPI with automatic address increment and the SDB rising edge resets the SPI interface. Typical applications include car display panel, ambient lighting, roof lighting, and functional lighting.
