There is an inverter output stage for AC induction, brushless DC (BLDC) and permanent magnet synchronous motors (PMSM), with separate open-source pins from low-side MOSFETs for three-phase current-sensing. An interface operates with 3.3 or 5V logic. Isolation rating is 1500V rms/min.
At Nuremberg, the company shared statistics around small electric motors, as used in dishwashers, air conditioners and fans. They account for up to 50% of total global energy consumption, which the company addresses with power management devices, such as the Motion SPM 7 modules, which include the FSB70xxx and which feature the FRFET technology, which was first introduced in the Motion SPM 5 modules.
The FRFET technology in the optimised gate driver for the built-in MOSFETs minimises EMI and losses, says the company, while also providing protection features in the form of under-voltage lockouts, thermal monitoring, fault reporting and interlock function.
The FSB70250, FSB70325 and FSB70625 are available in a PQFN package that can save up to 50% of board space, particularly limited in space conscious domestic appliances. The devices are accredited to Moisture Sensitive Level (MSL) 3.
There is also a free, online loss calculation tool available.
