STEVAL-IPMnMN Data brief 00 W motor control power board based on STIPNM50T-H SLLIMM nano IPM MOSFET Features Input voltage: from 5 to 00 VDC Nominal power: up to 00 W Nominal current: up to 0.6 Arms Input auxiliary voltage: up to 0 VDC Single- or three-shunt resistors for current sensing (with sensing network) Three options for current sensing: dedicated external op-amps, internal SLLIMM-nano op-amp (single) or via MCU Overcurrent hardware protection IPM temperature monitoring and protection Hall sensor or encoder input Intelligent power module: SLLIMM-nano IPM MOSFET-based (STIPNM50T-H full molded package) Motor control connector ( pins) interfacing with ST MCU boards Universal design for further evaluation with bread board and testing pins Very compact size RoHS compliant Description Product summary Compact motor drive power board STEVALIPMnMN SLLIMM-nano small low-loss intelligent molded module IPM, -phase inverter, A,.7 Ohm max., 500 V MOSFET STIPNM50T-H The STEVAL-IPMnMN is a compact motor drive power board based on SLLIMM nano (small low-loss intelligent molded module) MOSFET-based product (STIPNM50T-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 -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, 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 triple current sensing options: three dedicated on-board opamps, op-amps embedded on MCU or single internal IPM op-amp. The Hall/Encoder part 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-IPMnMN is compatible with ST s control board based on STM, providing a complete platform for motor control.
