The STEVAL-IPMNM5Q is a compact motor drive power board equipped with SLLIMM-nano (small low-loss intelligent molded module) 2nd series based on N-channel Power MOSFET MDmesh™ DM2 fast-recovery diode (STIPQ5M60T-H). It provides an affordable and easy-to-use solution for driving high power motors in 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 consists of six MOSFETs, three high voltage half-bridge gate driver ICs and a wide range of features like undervoltage lockout, smart shutdown, internal temperature sensor and NTC, overcurrent protection and internal op-amp.

The main characteristics of this evaluation board are small size, minimal BOM and high efficiency. It features an interface circuit (BUS and VCC connectors), bootstrap capacitors, snubber capacitor, hardware short-circuit protection, fault event signal and temperature monitoring. It is designed to work in single- or three-shunt configuration and with three current sensing options: three dedicated on-board op-amps, op-amps available on a connected microcontroller, or the single op-amp embedded in the power module. A Hall/Encoder section completes the circuit.

The system is designed to achieve accurate and fast conditioning of current feedback to satisfy the typical requirements for field oriented control (FOC).

The STEVAL-IPMNM5Q is compatible with ST control boards based on STM32 microcontrollers, providing a complete platform for motor control.
