The BCT3236 is a LED driver with independent 36 output channels, and the output current of each channel can be programmed to achieve 256 levels by I2C interface. The output current of each channel can be set at up to 38mA (Max.) by an external resistor and independently scaled by a factor of 1, 1/2, 1/3 and 1/4.
The chip can be turned off by pulling the SDB pin lowor by using the software shutdown feature to reduce power consumption.
BCT3236 is available in QFN5X5-44L (5mm × 5mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
