Introduction
The
is a compact motor drive power board equipped with SLLIMM™ (small low-loss intelligent molded
module) 2nd series based on n-channel power MOSFET MDmesh™ DM2 fast-recovery diode (
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, high-end power tools and 3-phase inverters for motor drives in general. The
IPM itself consists of 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
double current sensing options such as using three dedicated onboard op-amps, or op-amps embedded in the MCU. The Hall/
Encoder part completes the circuit.
Thanks to these advanced characteristics, the system has been specifically designed to achieve fast and accurate current
feedback conditioning, satisfying the typical requirements for field-oriented control (FOC).
The
is compatible with ST's STM32-based control board, enabling designers to build a complete platform for
motor control.
