Integrated MOSFET inverter module for low-power drive system

This paper introduces a new MOSFET inverter module for driving small brushless DC motors used in fans and water pump applications. The proposed power module integrates 6 MOSFETs and gate-driving high-voltage integrated circuits in a transfer-molded full-pack package. It provides optimized loss and EMC characteristics by using specially designed MOSFET and dedicated HVIC. This paper describes the package design, the MOSFET and the HVIC of the proposed module used in motor drive applications where power dissipation, electromagnetic interference and noise immunity are primary concerns.
