BL8582 Single-Wire Dimming, 3-Channels WLED Linear Drive DESCRIPTION The BL8582 is a CMOS based White/Blue LED driver with stand-alone capability. The driver is primarily designed for LED backlighting of LCD display powered by Li-ion battery With its high efficiency, low standby current and wide range of input supply voltage, the BL8582 is suitable for applications such as portable device display and keypad backlighting. It can realize dimming control through EN pin. Inner the device, there is a 4-bit counter, so the LED current can be set at 16 levels with 1/15 Imax step. BL8582 has three LED channels with a SOT-23-6 package. FEATURES • 2.7 to 5.5V input range • Single-wire dimming control with linear 16-steps. • PWM dimming control • LED sink current of max.
