The STEVAL-IPMM15B is a compact motor drive power board equipped with the SLLIMM (small low-loss intelligent molded module) 2nd series module 2nd series n-channel super junction MDmesh™ DM2 fast-recovery diode (STIB1560DM2T-L). It provides an affordable, easy-to-use solution for driving high power motors for a wide range of applications such as white goods, air conditioners, compressors, power fans, high-end power tools, and generally 3-phase inverters for motor drives.
The IPM itself consists of MOSFETs and a wide range of features including undervoltage lockout, smart shutdown, temperature sensing and NTC inside, and overcurrent protection.
The main characteristics of this evaluation board are its 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 signal and temperature monitoring. It is designed to work in single or three-shunt configuration and with two current sensing options: three dedicated op-amps on the evaluation board, or op-amps available on a connected microcontroller. 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-IPMM15B is compatible with ST control boards based on STM32 microcontrollers, providing a complete platform for motor control.
