The STK984-090A-E is a fully-integrated inverter power stage consisting of a gate driver, six MOSFET’s and a high-side shunt resistor, suitable for driving permanent magnet synchronous (PMSM) motors and brushless-DC (BLDC) motors. The MOSFET’s are configured in a 3-phase bridge with a single drain connection for the lower legs. The power stage has a full range of protection functions including cross-conduction protection, external shutdown and undervoltage lockout.
“This project is based on STK984-090A which is a fully-integrated inverter with current rating 20A and supply voltage 40V DC. It has been designed to drive the Brushless DC Motors (BLDC) and permanent magnet synchronous motors (PMSM), the module …
