The LP5524 device is a highly integrated dual-zone LED driver that can drive up to four LEDs in parallel with a total output current of 100 mA. Regulated high-side internal current sources deliver excellent current and brightness matching in all LEDs.
The LP5524 provides overcurrent protection and pulse-width modulation (PWM) control of four indicator LEDs without the need for external components.
LED driver current sources are split into two independently controlled banks for driving secondary displays, keypad and indicator LEDs. Brightness control is achieved by applying PWM signals to each enable pin. Default LED current is factory-programmable and an optional external resistor can be used to set LED current to user programmable values.
The LP5524 is available in a tiny, 9-pin, thin DSBGA package.
For all available packages, see the orderable addendum at the end of the data sheet.技術文件
