Краткое описание:
Four-Channel LED Driver With Dual-PWM Brightness Control
Дополнительная информация
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 100 mA. It features high-side internal current sources for current and brightness matching, PWM control without external components, and overcurrent protection. The device is split into two independently controlled banks (ENA and ENB) for driving secondary displays, keypads, or indicator LEDs. Default LED current is factory-programmable, and an optional external resistor can be used for user-programmable values.
