Abstract
According to an exemplary implementation, a power quad flat no-lead (PQFN) package includes a multi-phase power inverter, a control circuit, and a driver circuit. The driver circuit is configured to drive the multi-phase power inverter responsive to a control signal from the control circuit. The multi-phase power inverter, the control circuit, and the driver circuit are each situated on a PQFN leadframe of the PQFN package. The control circuit and the driver circuit can be in a common integrated circuit (IC). Furthermore, the control circuit can be configured to reconstruct at least two phase currents of the multi-phase power inverter from a combined phase current.
