LP3944 RGB/White/Blue 8-LED Fun Light Driver

LP3944 Description

LP3944 RGB/White/Blue 8-LED Fun Light Driver November 2003 LP3944 RGB/White/Blue 8-LED Fun Light Driver General .
LP3944 is an integrated device capable of independently driving 8 LEDs.

LP3944 Features

* n n n n Internal power-on reset Active low reset Internal precision oscillator Variable dim rates (from 6.25 ms to 1.6s; 160 Hz
* 0.625 Hz) Key Specifications n 8 LED driver (multiple programmable states
* on, off, input, and dimming at a specified rate) n 8 Open drain outputs capable

LP3944 Applications

* where it is required to cut down on bus traffic. Traditionally, to dim LEDs using a serial shift register such as 74LS594/5 would require a large amount of traffic to be on the serial bus. LP3944 instead requires only the setup of the frequency and duty cycle for each output pin. From then on, only
