Features

General Description

• 3 wind modes: Constant, Natural and Sleep

• 5 speed grades for each wind: Super-Strong,

Strong, Medium, Soft, Super-Soft

The PT8A986 can be used with Encoder PT8A982

to provide full control to an infrared remote control

fan. The PT8A986 has a group of output pins

corresponding to all functions. The received signal is

sampled, fault-tolerantly checked and decoded to

control the infrared remote control fan. The fan’s IR

system has three wind modes, five wind grades and

two timing modes. The PT8A986 has non-summable

timing mode in 1h, 2h, 4h and 8h if the A/N floats,

and has summable timing mode in 0.5h, 1h, 2h and

4h if the A/N connects to GND.

• 6 front buttons: Speed, Wind, R/L, U/L, Timer

and On/Off

• The Speed, Wind, R/L and U/L functions

rememberable

• Zero-cross trigger for TRAC protection

• Special protection for wrong key-in

• Two types of timing: summable and non-summable

• LED indicator

• Power on reset and LEDs lit for 2s

• The motor starts in strong wind

• The Buzz works when received right signal

• Wide operation supply voltage: 3.5V to 5.5V

• Two ways do the function: IR and front buttons

• 32KHz external crystal

The Motor starts or stops at the Zero-cross of the AC

power as an SYN input pin is used. The 50Hz AC

timed pulse input to this pin synchronizes the LL, L,

M, S and SS outputs. In the Natural and Sleep modes,

the wind speed is programmable.

• Low operation current

There is an internal inverter in the PT8A986. By

adding a 32KHz crystal, an oscillator can be

constructed.

• Few external components needed

• Programmable according to customer requirement

• Input I/Os adapt to most of IR Modules

• Package: 24-pin DIP or SOIC
