... V EE XDIS −14.7V 1. Power On Reset Fig.1 Block diagram showing the IES5528 as a mains phase controller. © 2009 Hendon Semiconductors, all rights reserved 2009 Nov 02, Revision 8.1 Phase Controller and Triac Triggering IC The IES5528 is mains powered, not requiring an expensive DC supply. It also provides an external DC supply rail for powering sensors and/or low power ICs ...

... Ds across optional diode Ds (refer to figure 1). During the positive half of the mains voltage cycle the external smoothing capacitor C1 supplies the IES5528. The IES5528 may also be powered with an external DC supply into V via a current limiting resistor. With V being the common pin, isolation CC requirements may need to be considered ...

... The reset circuit should not reactivate unless the voltage across the supply capacitor (C1) drops below approximately 7V. 6.3 Zero Crossing Detector The IES5528 contains a zero- crossing detector to produce pulses that coincide with the zero crossings of the mains voltage, minimising RF interference and transients on the mains supply. ...
