Abstract:
1. A bridge driver circuit with integrated charge pump, comprising: a driver circuit section of a charge pump capacitor wherein the driver circuit section is formed with power switch components and a diode network including a plurality of diodes, wherein: the diodes of the diode network are simultaneously elements of a bridge circuit section; the bridge circuit section includes a first bridge branch having a first bridge diver and a first charge pump capacitor, and a second bridge branch having a second bridge driver and a capacitor, and the diode network includes first and second pairs of series connected diodes, each pair connected between a power-supply voltage terminal and the first and second bridge drivers, wherein a first node between the diodes of the first pair of series connected diodes is connected to the first charge pump capacitor, and a second node between the diodes of the second pair of series connected diodes is connected to the second charge pump capacitor.
