FAN5646 blinking LED indicator circuit

This blinking LED indicator circuit is designed using FAN5646. The internal programmable blink algorithm eliminates any need for continual system processor control.
This FAN5646 blinking LED indicator circuit has a very low dropout voltage of 80mV which allows driving an LED without any inductors or switch capacitors. LED blink rate, rise and fall time, and CTRL line behavior can be programmed using TinyWire™ single-wire digital interface.

Main features of the FAN5646 blinking LED indicator are  : LED “Soft” Blink: with Logarithmic Fade Up and Fade Down for Power Savings , Follow or Repeat Pattern Mode for Blinking , Default Pattern Optionally Modified using TinyWire™ , High-Side Constant Current LED Driver , 35μA Operating Quiescent Current , Short-Circuit  Under-Voltage and Thermal Protections , Wide Input Range: 2.7 to 5.5V .
