ABSTRACT:
A "H" switching circuit for providing current drive to a load coupled between first and second outputs thereof comprising first and second paired switching transistor circuits each including an upper transistor that is cross-coupled at the first and second outputs to a respective paired lower transistor. The respective pairs of switching transistors are alternately rendered conductive whereby the polarity of the load current drive may be reversed. First and second transistors are provided with each being coupled respectively between a lower transistor of one of the paired switching transistor circuits and the upper transistors of the other one of the paired switching transistor circuits for severely limiting current spikes that otherwise occur during switching at the outputs of the switching circuit.
