The typical application shows a Back-EMF system configuration for a 6-step trapezoidal application and a shunt as a current limit sensor. The application circuit is also suited for a single-shunt FOC application, with the current limitation functionality of the single shunt and detection of wind milling via the Back-EMF sampler. The charge pump output (VCP) controls the reverse polarity protection N-channel MOSFET.
