ST’s motor-drive reference design packs a 3-phase gate driver, an STM32G0 MCU, and a 750-W energy stage on a round PCB that’s simply 50-mm in diameter. The small kind issue of the EVLDRIVE101-HPD board makes it appropriate for each house and industrial tools. It simply matches into handheld vacuums and energy instruments, in addition to drones, robots, and drives for industrial tools.
Leveraging the corporate’s STDRIVE101 3-phase gate driver, the reference design provides a wide range of driving strategies for brushless motors, together with trapezoidal or field-oriented management, with sensored or sensorless rotor-position detection. The IC comprises three half bridges with 600-mA supply/sink functionality and operates from 5.5 V to 75 V.
The facility stage of the EVLDRIVE101-HPD relies on 60-V N-channel energy MOSFETs with output present as much as 15 ARMS. Their low 1.2-mΩ on-resistance permits operation at very excessive load present, enabling energy supply as much as 750 W.
Builders can use the STM32G0 microcontroller’s single-wire-debug (SWD) interface to work together with it, whereas help for direct firmware updates allows simple utility of bug fixes and new options.
The EVLDRIVE101-HPD motor-control reference design prices $92.
