FAN5645 Indicator LED Blinker

The FAN5645 is a flexible and compact solution for a blinking LED indicator. The internal programmable blink algorithm eliminates any need for continual system processor control. This means longer battery life for the hand-held system because the system processor is not awakened from sleep mode just.

FAN5645 Features

* Records and plays back blink patterns

* Single-wire digital control of LED blink rate and intensity

* Resistor-programmable LED maximum current

* High-side constant-current driver topology: - 20mA maximum output - 40mV typical dropout at 20mA

* 33µA operating current

* Stan
