NTC Heating Controller with Multi LEDs
Features
Description
The PT8A3263/4/5/6/7/8 are mixed signal CMOS
LSI chips specially designed for heating controller with
the external NTC (Negative Temperature Component)
sensor. NTC open protection is implemented for device
safety and selectable 5 or 6 heating temperature levels.
PT8A3263/64 are for 5 step levels (eg.100℃,
120℃, 140℃, 160℃, 180℃) and PT8A3265/66 are for
6 step levels (eg. 100℃, 120℃, 140℃, 160℃, 180℃,
200℃). They can drive TRIAC or SCR directly and
detect the heater’s temperature with NTC sensor input.
They have up/down keys for temperature setting, On/Off
Key for heating on/off control and 3 LEDs display mode.
PT8A3267/68 have 6 step levels (eg.100℃, 120℃,
140℃, 160℃, 180℃, 200℃). They can drive TRIAC or
SCR directly and detect the heater’s temperature with
NTC sensor input. They have up/down keys for
temperature setting and On/Off Key for heating on/off
control. They also have 1 second (2 seconds for
PT8A3268A) delay function before go into off state and
lock-key function. Their LEDs have special running
flash mode (mode 4)
5/6 steps heat temperature settings with 5 LEDs or 6
LEDs indicator

NTC open protection
Pulse trigger for high current SCR / TRIAC (up to
15mA)
Auto power off after exact 1 Hour heating(It is
optional to disable.)
Dual Voltage (120/240V 50/60Hz) operations (only
PT8A3263-3266A/B/C available)

These devices can be used in both 120V and 240V
power line system, as they can automatically adjust the
heating power according to the power line voltage to
avoid heating appliance damage or long heating time.
They have selectable build-in timer to enable/
disable auto-power off function after turn on 1 hour and
the timer is 1 hour both under 60Hz and 50Hz power
supply.

Functional Description
Input Button
1) Mode 1
Standby/Off state: LED1 ~ LED6 are all off
On State: The LED that be setting level is on.
2) Mode 2
Standby/Off state: LED1 ~ LED6 are all off
On state:
Heating up: The LED that be setting level is Flash. (Fclk/32)
Stable: This LED is on
Drop: This LED is on
For PT8A3263/64/65/66
1) Up button: Temperature up adjustment. Push it once the
temperature setting will increase one level until the
highest level is reached.
2) Down button: Temperature down adjustment. Push
Down button once, the temperature setting will reduce
one level until the lowest level is reached.
3) On/Off button: This button is toggled on Heating-on
state and Heating-off state.
For 1-key mode, this key will be set the temperature by loop:
Off12345(6)Off
When power on IC first, the initial temperature setting is
Level 4 (Internal option: Level1)
Delay function:
Heating-on & Heating-off has no delay
(Internal option: Heating-on has 0.5 second delay & Heating-
off has 1 second delay).
4) C1: When in ON state, C1 output high.
3) Mode 3
Standby/Off state: LED1 ~ LED6 are all off
On state: The LED that be setting level and below the
setting level are on.
4) Mode 4
Standby/Off state: LED1 ~ LED6 are all off
On state:
Level 1:
Heating up/ Drop: LED1 is flash (Fclk/32)
Stable: LED1 is on
Level2:
For PT8A3267A/68A
Heating up/ Drop: LED1 and LED2 is round flash (Fclk/16)
Stable: LED1 and LED2 are on
Level4 ~ Leve6: similar as upon
1) Up button: Temperature up adjustment. Push Up button
once, the temperature setting will increase one level until
the highest level is reached.
Note:
2) Down button: Temperature down adjustment. Push
Down button once, the temperature setting will reduce
one level until the lowest level is reached.
3) On/Off button: This button is toggled on Heating-on
state and Heating-off state.
1.When in stable state, don’t flash even if detect the below or
over setting temperature(for mode2 and mode4)
2.When push up/down key, the setting LED will be on state
for 1.5s before starting flashing(for mode2 and mode4)
3.When push up/down key, the setting LED will be forced to
flash for 2.5s (for mode4)
PA8A3267A: When power on IC first, the initial temperature
setting is Level 4
5) NTC open state
PA8A3268A: When power on IC first, the initial temperature
setting is Level 6
The LED that relate with the setting temperature is fast
flash (Fclk/8)
If power is always on IC, the last setting temperature level will
be memorized when push ON again
Disable up/down key function
If detect NTC is not open, recover working state
Delay function:
6) LED drive style
PT8A3267A: Heating-on has no delay & Heating-off has 1
LED1-LED6: High pulse drive (50Hz)
second delay
C1: High level drive, PT8A3267/68A use pulse drive (50Hz)
PT8A3268A: Heating-on has no delay & Heating-off has 2
second delay
4) C1: Lock key function
Reset
After power on, the chip will be reset by internal POR
circuit, GATE, LED and C1 pins output low level and IC is
in Standby state
When in Heating-on state, after continuously push
on/off key down twice( The interval is less than 600ms ),
IC will lock current temperature level state and disable
up/down and on/off function, C1 pin output high level
Timer
When in lock state push on/off key down twice again,
IC will unlock current temperature level state and enable
up/down and on/off function, C1 pin output low level
Once IC enters Heating-on state, internal timer will
start to count. It’ll be timeout and auto heating-off after
exact 1 hour both under 60Hz and 50Hz. This function
can be disabled by Pin TM is tied to ground.
LEDs indicator:
The timer will be clear while push up/down key.
LED1: Level 1 temperature setting ( eg. 100℃)
LED2: Level 2 temperature setting ( eg. 120℃)
LED3: Level 3 temperature setting ( eg. 140℃)
LED4: Level 4 temperature setting ( eg. 160℃)
LED5: Level 5 temperature setting ( eg. 180℃)
LED6: Level 6 temperature setting ( eg. 200℃, for
PT8A3265/6x, PT8A3267A/68A)
Control signal output
When working in Heating-on state, Gate output will be
related to NTC1 input and CLK input amplitude.

Effect of NTC and Pulse Trigger on GATE
a) High trigger peak current (>15mA), enough trigger 15A triac
b) Pulse triggering reduce the false self trigger by the leakage of triac at high temperature environment.
c) Tal_GATE = 300us (Internal option: 600us, 900us)
d) 120VAC input, under half power state, the minimum heating-period is 32 cycles (Internal options: 8, 16, 32, 64 cycles)
e) The drive pulse present at both positive edge and negative edge (Internal option: only positive edge)
