The MM32Spin is a family of products designed specifically for motor and power-related applications. It uses high-performance ARM Cortex-M0 and ARM Cortex-M3 cores and is divided into dedicated MCU and drive MCU based on the functional area. The MM32Spin series provides up to 128KBFlash, with built-in multi-channel UART, I2C, SPI, CAN and a variety of high-precision analog peripherals, including: comparator, 12-bit 3MSPSADC and operational amplifier. Driving MCU provides the function of integrated power supply, predrive, LDO, MOSFET and other rich peripherals, the planned voltage range is 20V, 60V, 200V and 600V, rich products and applications cover a wide range.

The MM32SPIN423C low-voltage single-chip motor driver integrates a high-performance ARM Cortex-M0 microcontroller core with a maximum operating frequency of 96 MHz, charge pump gate drive circuit and power MOSFET, and carries a maximum 3A(RMS) drive current in a 4×4mm QFN32 minimal package. It can realize the ultra-quiet and efficient solution of double-resistor sampling or single-resistor sampling in the three-phase brushless DC motor (BLDCM)FOC driving algorithm with very few peripheral devices. It has a backpotential detection resistor voltage division network built in, so as to achieve ultra-small PCBA area, low noise and low power consumption. Suitable for hand-held head, servo steering gear, server cooling fan and other small portable equipment.

The MindSpin platform promoted by MindSpin covers two directions of IC technology and motor drive technology. IC technology breakthrough, including the integration of Gate Driver technology, as well as all-in-one technology, not only the Gate Driver integration, more includes LDO and MOSFET, in the motor drive dedicated MCU field, played an important role. In terms of driving technology, the technologies brought by MindSpin Motor SDK, such as high speed Motor drive, not only improve the running speed of the Motor, but also improve the efficiency value. At the same time, due to the integration of many power peripherals, the circuit board is more streamlined, and the volume rate and quality are improved, bringing better cost advantage and competitiveness.

The MindSpin platform not only provides a variety of professional MCU products, but also provides the core high efficiency motor drive algorithm. Compared with the inelasticity of ASIC and other hardware drivers in the market, the driver products with 32-bit MCU as the core can not only have more flexibility in algorithm application, but also allow customers to maintain more technical autonomy and flexibility in product development.
