FAN5646

Programmable Indicator “Soft” LED Blinker with TinyWire™

Single-Wire Interface

Features

Description

The FAN5646 is a flexible and compact solution for a blinking

or “breathing” LED indicator. The internal programmable blink

algorithm eliminates any need for continual system processor

control. This means longer battery life for a hand-held system

because the system processor is not awakened from sleep

mode to blink an LED.

LED “Soft” Blink: with Logarithmic Fade Up and Fade

Down for Power Savings

Follow or Repeat Pattern Mode for Blinking when

Applications Processor is Powered Down

Default Pattern Optionally Modified using TinyWire™

Single-Wire Digital Control for:

Very low dropout of 80mV allows driving an LED without any

inductors or switch capacitors. LED blink rate, rise and fall

time, and CTRL line behavior can be programmed by a

TinyWire™ single-wire digital interface. The on-time and time

between pulses can be set for up to two different pulse widths.

–

LED Current Rise / Fall Time

t_ONand t_OFFfor Up to Two Pulses

High-Side Constant Current LED Driver:

–

20mA Maximum Output Current

80mV Drop-out at 20mA I_OUT

The default for FAN5646 option 01 is “follow” mode, where the

LED turns on with the programmed rise time, then stays on as

long as CTRL remains HIGH. When CTRL falls, the LED turns

off at the programmed fall time. For option 00; when CTRL is

HIGH continuously, the LED repeats the programmed pattern.
