NTC+LCD Heating Controller
Features
Description
LCD screen showing temperature setting
Dual Temperature (Fahrenheit/Centigrade) Display
Backlights indicating work status
Auto temperature control with NTC
8 and 11 temperature levels option
Three keys: On/Off, Up and Down
NTC open protection
Pulse trigger for high current SCR/TRIAC (up to
15mA)
1 hour auto power off.
Dual Voltage (120V/240V) operations
Internal 5V zener
Lead free and Green QFN-24TSSOP-24 and
SOIC-24 package; Lead free DIP-24 package
The PT8A336x is a mixed signal CMOS LSI chip
designed as heating controller with help of external NTC
(Negative Temperature Component). NTC open
protection is implemented for device safety and 11
temperature levels. It can drive TRIAC or SCR directly.
It has 3 keys function setting. LCD displays and
backlight indicate the working status.
This device can be used in both 120V and 240V power
line supplier, as it will automatically adjust the heating
power according to the power line voltage to avoid
heating appliance damage or long heating time.
The PT8A336x build-in timer will be auto-power off
after power on 1 hour both 60Hz and 50Hz.
