TEA1024/ TEA1124
Zero Voltage Switch with Fixed Ramp
Description
The monolithic integrated bipolar circuit, TEA1024/
TEA1124 is a zero voltage switch for triac control in
domestic equipments. It offers not only the control of a
triac in zero crossing mode but also the possibility of
power control. This is why the IC contains a mains
synchronized ramp generator with 640 ms (1280 ms)
duration (50 Hz). It is suitable for a typical load of 750 W
(1000 W) meeting the Flicker Standard. (values in
brackets relate to TEA1124.)
Features
D Direct supply from the mains
D Definite IC switching characteristics
D Very few external components
D Full wave drive – no dc component in the load circuit
D Current consumption 1.5 mA
D Output short circuit protected
D Simple power control
D Integrated ramp generator
D Reference voltage variable by external resistance
D Pulse position optimization

Supply Voltage
Due to higher trigger sensitivity of the triac it is supplied
with negative signal. It can be supplied via diode and
series resistance from the negative half wave of the mains.
An internal parallel controller limits the voltage between
Pin 5 and 7 to a typical value of 6.55 V.
