Applications
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.
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.
