Description: 8 Channel LED Driver

Features

* Drive Common Anode or Common Cathode LEDs
* Low 50mV Dropout at 20mA
* 20mA full scale current
* One Wire interface for 8-Step Brightness Control
* 2.7V to 5.5V Supply Voltage Range
* Thermal Shutdown Protection
* Low Input Noise and EMI

Applications

* significantly improved efficiency. The BCT3228 requires only a 50mV dropout voltage at a 20mA load on each output to match the LED brightness. By using two SEL pin, the BCT3228 can support to drive 8 parallel Co-Anode or Co-Cathode white LEDs and regulates a constant current for uniform intensity.
