PT2128A is a high performance electronic fan controller from Princeton Technology Corp. It features high performance, low power consumption, DIP or SO package, optional independent light control, 90 seconds cycle/6 seconds/step(off step 3 seconds) rhythm wind pattern, four operation modes(ordinary, rhythm, ordinary sleep and rhythm sleep), memory startup mode, 2-3 seconds middle wind startup(mask option).
The PT2128A is a high‑performance CMOS remote fan controller IC that integrates speed control, timer, rhythm wind, sleep mode, swing‑head and light control in a single chip. It provides LED, buzzer, key inputs and built‑in remote decoding for compact fan designs.
The device is offered in various DIP and SO packages ranging from 16 to 24 pins, supports up to three swing‑head or light outputs, and includes four operation modes (ordinary, rhythm, ordinary‑sleep, rhythm‑sleep). Application circuits and pin configurations are provided for easy PCB layout.
