FAN5645 Description
The FAN5645 is a flexible and pact 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 to blink an LED.
