STEVAL-IPMnM2N motor control power board based on the SLLIMM-nano? 2nd series

The STEVAL-IPMnM2N is a compact motor drive power board based on SLLIMM-nano? （small low-loss intelligent molded module） 2nd series IPM MOSFET-based （STIPN2M50T-H）。 It provides an affordable and easy-to-use solution for driving high power motors for a wide range of applications such as power white goods， air conditioning， compressors， power fans and 3-phase inverters for motor drives in general. The IPM itself consists of short-circuit rugged MOSFETs and a wide range of features like undervoltage lockout， smart shutdown， embedded temperature sensor and NTC， and overcurrent protection.

The main characteristics of this evaluation board are small size， minimal BOM and high efficiency. It consists of an interface circuit （BUS and VCC connectors）， bootstrap capacitors， snubber capacitor， hardware short-circuit protection， fault event and temperature monitoring. In order to increase the flexibility， it is designed to work in single- or three-shunt configuration and with triple current sensing options： three dedicated onboard op-amps， an internal IPM op-amp and op-amps embedded in the MCU. The Hall/Encoder section completes the circuit.

With these advanced characteristics， the system is designed to achieve fast and accurate current feedback conditioning， satisfying the typical requirements for field-oriented control （FOC）.The STEVAL-IPMnM2N is compatible with ST’s STM32-based control board， enabling designers to build a complete platform for motor control.
