ST’s New Motor-Drive Reference Design in Circular PCB Eases Plug-and-Play Connection

STMicroelectronics new EVLDRIVE101-HPD (High Power Density) motor-drive reference design is a circular PCB with a diameter of just 50mm that houses a 3-phase gate driver, STM32G0 microcontroller, and 750W power stage.ST EVLDRIVE101-HPD motor-drive reference design the volt post

The Motor-Drive Reference Design Board Features:

  • Extremely low power consumption in sleep mode, below 1uA,
  • And its tiny outline can fit directly in equipment like hairdryers, handheld vacuums, power tools, and fans.
  • It also fits easily into drones, robots, and drives for industrial equipment such as pumps and process-automation systems.

Built with ST’s Robust and Compact STDRIVE101 3-Phase Gate Driver, the Reference Design Gives:

  • Flexibility to choose the motor-control strategy, such as trapezoidal or field-oriented control (FOC), with sensored or sensorless rotor-position detection.
  • The STDRIVE101 IC contains three-half bridges with 600 mA source/sink capability and operates from 5.5V to 75V to handle any low-voltage application.
  • The chip integrates voltage regulation for the high-side and low-side gate drivers and configurable drain-source-voltage (Vds) monitoring protection.
  • It also provides an external pin for choosing direct high-side and low-side gate inputs or PWM control.

Developers can take advantage of the STM32G0 single-wire debug (SWD) interface to interact with the microcontroller, while support for direct firmware update allows applying bug fixes and new features.

The Power Stage of the EVLDRIVE101-HPD Reference Design Features:

STL220N6F7 60V STripFET F7 MOSFETs, which preserve efficiency with their 1,2m? typical Rds(on), easing plug-and-play connection of the motor.

Additional Features Include:

  • Fast-acting power-on circuitry that disconnects the power source when idle to save energy and extend operation in battery-powered applications.
  • Protection built into the driver IC ensures system safety and efficiency, including the Vds monitoring of the power-stage MOSFETs, as well as under-voltage lockout (UVLO), overtemperature protection, and cross-conduction prevention.

 Availability and Pricing

The EVLDRIVE101-HPD is ready to use out of the box and is available now from the eSTore, for $92.00.
