PT2128A

Description

PT2128A 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.
