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.
Features
- 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.
- LED to indicate operation status.
- Usable in both 120V and 240V voltage supply
system.
- Quick function test mode.
- Support buzzer.
- Few external components.
- System standby mode power dissipation less than
1W (Base on recommended application circuits).
- DIP-8 and SOIC-8 package.
- Patent No: ZL 2005 2 0048330.4.
