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.
Very low dropout of 80 mV 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.
The default for FAN5646 option 01 is “ f ollow” 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.
The FAN5646 is available in a four-pin wafer-level chip-scale
package with 0.4 mm pitch or a five-lead SC70 package.
