Abstract
A current sensing circuit is described. The current sensing circuit is for sensing a high side current through a high side switch and/or for sensing a low side current through a low side switch of a half bridge comprising the high side switch and the low side switch, which are arranged in series between a high side potential and a low side potential. The high side switch and the low side switch are in respective on-phases in a mutually exclusive manner. The high side sensing circuit comprises mirroring circuitry to mirror a current from a first node of the high side sensing circuit to an output node of the high side sensing circuit. The current sensing circuit comprises a low side sensing circuit to provide a sensed low side current which is indicative of the low side current during an on-phase of the low side switch.
