The LP5524 is a highly integrated dual-zone LED driver that
can drive up to four LEDs in parallel with a total output current
of 100mA. Regulated high side internal current sources deliver
excellent current and brightness matching in all LEDs.
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.
