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 controllers. · Their intelligence stems from sensitive detection of the movement and static position of the electric iron using a special sensor. · These chips can detect the vertical/horizontal position and movement status of the iron. · They include an on-chip shunt regulator, sensor signal processor, built-in oscillator, timer, logic control, power-on reset, and output driving block.

FEATURES

· Built-in RC oscillator for sensor signal detection. · On-chip shunt regulated power supply. · Uses AC 60Hz/50Hz as a timer clock, selectable by part number. · Accurate timer with an error margin of ±1%. · Sensitive movement detection. · Strong immunity to sensor vibration. · 30s timeout for iron in a static horizontal position. · 8min/10min/15min timeout for iron in a static vertical position. · LED to indicate operation status. · Compatible with both 120V and 240V voltage supply systems. · Quick function test mode. · Supports buzzer. · Requires few external components. · System standby mode power dissipation less than 1W (based on recommended application circuits). · Available in DIP-8 and SOIC-8 packages. · Patent No: ZL 2005 2 0048330.4.
