Patent ID: 7466116

Claim:
An integrated circuit, comprising: a high-side switch array coupled through a first bonding wire and a first bonding pad between a high-voltage terminal and an output terminal, a low-side switch array coupled through a second bonding pad and a second bonding wire between a low-voltage terminal and the output terminal; a driver coupled to the switch arrays for driving the switch arrays; and a current sensing circuit comprising at least one of: a high-side sensing circuit coupled to the first bonding pad to detect a signal passing through the first bonding wire wherein: a first terminal of the first bonding wire is coupled through a first resistor to an inverting input of a first amplifier; a second terminal of the first bonding wire is coupled to the noninverting input of the first amplifier, and an output of the first amplifier is coupled through a second resistor to the noninverting input of the first amplifier; and a low-side sensing circuit coupled to the second bonding pad to detect a signal passing through the second bonding wire wherein: a first terminal of the second bonding wire is coupled through a third resistor to an inverting input of a second amplifier; a noninverting input of the second amplifier is coupled to ground; and an output of the second amplifier is coupled through a fourth resistor to the noninverting input of the second amplifier.
