产品概述
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.
