Heating Controller

Features

Description

The PT8A3230/1/2/3/14/5/6/7 is a mixed signal

CMOS LSI chip designed for the automatic controller of

heat with external NTC (Negative Temperature

Component). NTC open protection is implemented for

device safety. When NTC is open, it will cut off GATE

output to disable heating, and the LED1 will flash at 1/8

CLK.

 Dual Voltage (120V/240V) operations

 Auto temperature control with NTC

 NTC open protection

 Multi mode LED indicator

 Direct drive SCR

 Auto Heating off after heating timer timeout

 Low cost 8-Pin DIP and SOIC package

The device can be used in both 120V and 240V

power line supplier, automatically adjusting the heating

power according to the power line voltage to avoid

heating appliance damage.

Applications

 Hair Curler
