Smart Iron Controller
Features
Description
The PT8A3514/15/16/17/18/19(A/B) are high
performance low power and low cost CMOS chips
designed for intelligent electric IRON controller. Their
intelligence mainly results from their sensitive detection
to the movement and static position of electric iron by
using a special sensor. With the sensor, these chips can
detect the vertical/horizontal position and movement
status of IRON.
Build in RC oscillator for sensor signal detection
On chip shunt regulated power supply
Using AC 60Hz/50Hz as timer clock can select by
Part No.
Accurate timer with error dropping in ±1%
Sensitive movement detection
Powerful immunity of sensor Vibration
30s time out for IRON in static horizontal position
8min/10min/15min time out for IRON in static
vertical position
These chips are equipped with on-chip shunt
regulator, sensor signal processor, build-in oscillator,
timer, logic control, power on reset and output driving
block etc.
LED to indicate operation status

Functional Description (Refer to Block Diagram)
The chip is comprised of several blocks: on-chip shunt regulator, sensor signal processor, build-in system oscillator,
30s/8min/10min/15min timer, logic control circuit, and power on reset, etc. Each block will be described as below.
Logic control circuit
Logic control circuit mainly carries out logic control function. It not only collects signals from other blocks, but also generates
various driving signals including RELAY&DISC. Besides, an external LED will flash at about 1Hz and a buzzer will make a
sound with a frequency of 4KHz every 0.5s for 6 times or continual after internal timer times out. Signals at RELAY will control
external relay to decide whether IRON heats or not.
Sensor signal processor
The core in the whole system is how to correctly detect the position and movement of sensor so that the system can be always
under safe control. Thus, it is critical to accurately and correctly deal with signal from sensor in different status and eliminate the
noise caused by debounce action from sensor. Here, a unique structure is used to do the high-requirement signal processing.
In real application of IRON, sensor needs to be installed according to certain requirements (for example its inclination).
Timer
Timer block mainly generates various timing signal according to the position of IRON.
It is easy to get accurate timer (30s/8min/10min/15min) by using AC 60Hz/50Hz signal as timing reference. As above description,
Iron in Horizontal position over 30s will stop heating. While Iron in vertical position over 8min/10min/ 15min will also stop
heating.
Buzzer
A buzzer will make 0.5S sound with a frequency of 4 KHz for 6 times or continual after internal timer timeouts.
LED
During heating, LED pin is floating and an external LED will turn on. After times out, LED pin outputs pulse and an external LED
will flash at about 1Hz.
