“One Hour” Programmable Fan Controller

PT2120

Description

PT2120 is a programmable fan controller IC utilizing CMOS Technology specially designed in a new

revolutionary concept. PT2120 may be programmed according to your customer’s special requirement

at least cost and shorter development time. Hands-on experience in developing and programming the fan

controller functions such as wind pattern, timer scale, and other add-on features such as remote control

decoding circuitry in less than an hour is only possible with PT2120 (Demo Kit). Thus, the PT2120 is

popularly dubbed as “The One Hour Programmable Fan”. One advantage of PT2120 is that

reprogrammable. This means that the user is able to repetitively make modifications until he is satisfied

with his fan design features at no additional costs. The programmed PT2120 (Demo Kit) may then be

used for immediate function testing as well as pilot run.

Housed in a 28-pin DIP or SO Package,

PT2120 incorporates custom-design functions with PTCs high performance and long term reliability

features making it the ideal answer to every fan and other electronic household application need.
