LP3943 - White-LED Driver

Description

The LP3943 is an integrated device capable of independently driving 16 LEDs.

This device also contains an internal precision oscillator that provides all the necessary timing required for driving each LED.

Two prescaler registers, along with two PWM registers, provide a versatile duty-cycle control.

Features

  • 1 Internal Power-On Reset.
  • Active Low Reset.
  • Internal Precision Oscillator.
  • Variable Dim Rates (From 6.25 ms to 1.6 s; 160 Hz to 0.625 Hz).
  • 16 LED Drivers (Multiple Programmable States: ON, OFF, Input, and Dimming at a Specified Rate).
  • 16 Open-Drain Outputs Capable of Driving up to 25 mA per LED 2.
