UAA2016

Zero Voltage Switch

Power Controller

The UAA2016 is designed to drive triacs with the Zero Voltage

technique which allows RFI−free power regulation of resistive loads.

Operating directly on the AC power line, its main application is the

precision regulation of electrical heating systems such as panel heaters

or irons.

A built−in digital sawtooth waveform permits proportional

temperature regulation action over a ±1°C band around the set point.

For energy savings there is a programmable temperature reduction

function, and for security a sensor failsafe inhibits output pulses when

the sensor connection is broken. Preset temperature (i.e. defrost)

application is also possible. In applications where high hysteresis is

needed, its value can be adjusted up to 5°C around the set point. All

these features are implemented with a very low external component

count.

UAA2016 CIRCUIT FUNCTIONAL DESCRIPTION Power Supply (Pin 5 and Pin 7) Sawtooth Generator The application uses a current source supplied by a single high voltage rectifier in series with a power dropping resistor. An integrated shunt regulator delivers a VEE voltage of − 8.6 V with respect to Pin 7. The current used by the total regulating system can be shared in four functional blocks: IC supply, sensing bridge, triac gate firing pulses and zener current.
