Power Factor Controller IC for High Power Factor and Active Harmonic Filter

Siemens AG 

TDA 4814

Output Driver

The output driver is intended to drive a SIPMOS transistor directly. It is designed as a push-pull

stage.

Both the capacitive input impedance and keeping the gate level at zero potential in standby

operation by an internal 10-kΩ-resistor are taken into account. Possible effects on the output driver

by line inductances or capacitive couplings via SIPMOS transistor Miller capacitance are limited by

diodes connected to ground and supply voltage.

Ground Pins

Between the ground pins GND and GND QSIP, a very close and low-impedance connection is to

be established.

Monitoring Circuit (I START, I STOP, Q START, Q STOP)

The monitoring circuit guarantees the secure operation of subsequent circuitries.

Any circuitry that is shut down because of a fault, for instance, cannot be started up again until the

monitoring start (I START / Q START) has turned on and a positive voltage pulse has been

impressed on Q START. This function starts for example the lamp generator of an electronic ballast

or generates auxiliary trigger signals for the detector input.

If there is a defect present (e.g. defective fluorescent lamp) the monitoring stop (I STOP /

Q STOP) will shut down either the entire unit or simply the circuitry that has to be protected. No

restart is possible then until the hold current impressed on I START or Q STOP has been

interrupted (e.g. by a power down).
