SCR
Enhanced MHP Algorithm for Quickly Heating-Up
and Quickly Lost-Heat-Recover
Uniform Heat to Maintain Constant Temperature
Adjustable to fit wide range heating plates
Adjustable to different Thermal Coefficient of
Resistively
Full compensation and insensitive to environment

6 Heat Temperature Settings
Auto power off for PT8A3251
Over Temperature protection
Package: DIP-16 and SOIC-16 package
The PT8A3251/53 is a Mix-signal CMOS chip
designed for ceramic heating controller. The chip offers
6 different default heat temperature settings including
150C, 170C, 185C, 200C, 215C, 230C. And the
temperature range can be adjusted through external
series resistance. The PT8A3251 has an internal timer; it
timeouts and device will stop heating automatically after
216000 clock period, ie. 1 hour for 60Hz and 1.2 hour
for 50Hz. The PT8A3251/53 also has over temperature
protection function. The chip is enclosed in Lead free
DIP-16 and SOIC-16.

Functional Description
3 Input Buttons
On/Off: This button will toggle Heating-on or
Heating-off. Once heating-on, the level 4 of 200C
temperature setting always be selected.
Up: Temperature up adjustment button. Push Up-
button once, the temperature setting increases one
level until the highest level 6. Then after, Level 6 will
be kept.
Down: Temperature down adjustment button. Push
Down-button once, the temperature setting reduces
one level until the lowest level 1. Then after, Level 1
will be kept.
7 LED Indicator
LED1: Heating-on or Heating-off
LED2: 150C temperature setting (level 1)
LED3: 170C temperature setting (level 2)
LED4: 185C temperature setting (level 3)
LED5: 200C temperature setting (level 4)
LED6: 215C temperature setting (level 5)
LED7: 230C temperature setting (level 6)
Note: The temperature range can be adjusted by
external series resistance.
Reset
After power on the chip will be reset by POR circuit,
LED1~ LED7 are all disabled. GATE and OT PIN
output are low level.
Timer (Only for PT8A3251)
Once IC enters Heating-on state, internal timer starts to
count. It timeouts and device will stop heating
automatically after 216000 clock period, ie. 1 hour for
60Hz and 1.2 hour for 50Hz.
Over-Heat Protection
Once heater loses control and reaches to 280C, the
Over-Heat protection function will be activated by
driving one SCR to melt the fuse immediately.
