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 PT8A 3265/66 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 ha ve 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) These devices can be used in b oth 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 b uild-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.

2015-07-0002 PT0326-2 09/29/15 PT8A3263-66A-F/67A/68A NTC Heating Controller with Multi LEDs Functional Description Input Button 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: 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. For PT8A3267A/68A 1) Up button: Temperature up adjustment. Push Up button 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. PA8A3267A: When power on IC first, the initial temperature setting is Level 4 PA8A3268A: When power on IC first, the initial temperature setting is Level 6 If power is always on IC, the last setting temperature level will be memorized when push ON again Delay function: PT8A3267A: Heating-on has no delay & Heating-off has 1 second delay PT8A3268A: Heating-on has no delay & Heating-off has 2 second delay 4) C1: Lock key function 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 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 LEDs indicator: 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) 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 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: Heating up/ Drop: LED1 and LED2 is round flash (Fclk/16) Stable: LED1 and LED2 are on Level4 ~ Leve6: similar as upon Note: 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) 5) NTC open state The LED that relate with the setting temperature is fast flash (Fclk/8) Disable up/down key function If detect NTC is not open, recover working state 6) LED drive style LED1-LED6: High pulse drive (50Hz) C1: High level drive, PT8A3267/68A use pulse drive (50Hz) 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 Timer 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. The timer will be clear while push up/down key. Control signal output When working in Heating-on state, Gate output will be related to NTC1 input and CLK input amplitude.
