Abstract
According to an exemplary implementation, a power quad flat no-lead (PQFN) package includes a multi-phase inverter situated on a leadframe. The PQFN package further includes drivers situated on the leadframe and configured to drive the multi-phase inverter. The PQFN package also includes bootstrap diodes respectively coupled to the drivers. The bootstrap diodes are in a common integrated circuit (IC) that is situated on the leadframe. The common IC can include the drivers. The drivers can be high side drivers that are coupled to high side power switches of the multi-phase inverter. Also, the bootstrap diodes can be coupled to a supply voltage terminal of the PQFN package. Furthermore, the PQFN package can include wirebonds coupling the common IC to bootstrap supply voltage terminals of the PQFN package.
