REMOTE FAN CONTROL IC
DESCRIPTION
The SC2128A is a high performance electronic fan controller LSI,
Speed control, off-timer, rhythm wind, sleep mode, head swing
and/or light control are all built into a single chip. Indicator LED
output, buzzer output, key control input, as well as remote control
decoding circuitry are all provided to build a full function electronic
fan with remote control capability having the highest performance
with the least external components. Pin assignment and application
circuit are optimized for easy PCB layout and cost saving for
electronic fan application.
