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 to blink an LED. Very low dropout of 40mV allows driving an LED without any inductors or switch capacitors. An external resistor sets the LED output current level. LED blink rate and intensity is controlled by a simple one-wire interface. In shutdown mode, the supply current is reduced to 0.3µA (typical
