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

repeating signal, function, or series of emends.
2. The tune between two consecutive transients of the
pointer or indicating means of an electrical indicating
instrument in the same disdain the rest position.
Something called periodic fine.
Comparator
The comparison of set value and measured value is
carried out via the two comparator inputs Pin 1 and Pin 2.
Here Pin 2 is the inverting input and has a circuit pro-
tecting it against interference spikes. Figure 5 shows the
protective circuit of the comparator. Pin 1 is the non-
inverting input.
