The external switch circuit (23) switches the signal supply route and successively transmits the supplied signals via an external antenna (24).

The device (1) can further comprise an alternating voltage source (6) which is able to supply a voltage (U5) required for commutating the externally commutated power converter (9).

A switching circuit selectively switches the signal path of the one or the other portion of the horizontal slot line to the vertical slot line according to an external switching control signal.

Designed in the integrated circuit (IS) is an internal switching end stage (ISE) for coupling to an external switching end stage (ESE) located outside the integrated circuit (IS) by way of the driver output (IS_AUS).

An AC-DC power converter controls an external upstream switching device, which supplies it power to be converted.

This means that the refrigerant circuit is reversed internally or reversal is achieved by an external changeover of the primary and secondary circuits.
