PT2129A
Description
PT2129A is a high performance electronic fan controller LSI. Speed control, on-timer, off-timer,
rhythm wind, sleep mode, head swing and/or light controls 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 assignments and application circuit are optimized
for easy PCB layout and cost saving for electronic fan application.
