| PT8A3361/62/63/64 NTC+LCD Heating Controller • 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 TSSOP-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. • Heating Controller Block Diagram 12-07-0006 PT0356-1 07/06/12 1 |||||||||||||||| PT8A3361/62/63/64 NTC+LCD Heating Controller |||||||||||||||||||||||||||||||||| Pin Information Pin Configuration PT8A3361/62/63/64 Pin Description Pin No. Name 1, 19 20, 21, 22, 24, 23, 2 3,4,5,6 7 8 9 10 11 12 13 14 15 16 17, 18 SEL2,SEL1 SEG1,SEG2, SEG3,SEG4, SEG5,SEG6, COM1,COM2 COM3,COM4 C/F NTC1 NTC2 GND CLK K2 K1 VDD GATE BL1 NC Type I O I O Power I Power O - Description Select temperature setting 00 100C~200C 01 130C~230C;10 120C~220C 11 160C~230C.
