Power modules are fully integrated inverter power stages

ON Semiconductor NFAQ1060L33T and NFAQ1060L36T Intelligent Power Modules, available now from Mouser, are fully integrated inverter power stages. They comprise of a high-voltage driver, six IGBTs, and a thermistor.

The devices are ideal for driving permanent magnet synchronous motors, brushless-DC motors, and AC asynchronous motors. The IGBTs are configured in a three-phase bridge with separate emitter connections for the lower legs for highest flexibility in the selection of control algorithm. The power stage has a comprehensive range of protection functions, incorporating cross-conduction protection, external shutdown, and undervoltage lockout functions. An internal comparator and reference connected to the overcurrent protection circuit provide for setting the overcurrent protection level.

Typical applications include industrial fans, washing machines, air conditioners, and pumps.
