REMOTE FAN CONTROL IC
DESCRIPTION
The SC2128C 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.
FEATURES
* High performance CMOS Technology
* Low power consumption
* Optional independent light control
* 90 seconds cycle/6 seconds per step(off step 3 seconds) rhythm
wind pattern
* Built-in remote control decoding circuitry with mask option
custom code
* Available in 16,18,20,22,24 pin package for none, one set or two
sets of swing head and/or light control
* Two sets of swing head and/or light control
* Three operation modes: ordinary, rhythm and rhythm sleep.
DIP-24-300-2.54
APPLICATIONS
* Optimized for fan application
* Suitable for heater fan, cooling fan,
and other home appliances with remote
control, timer and/or output level control
