STMicroelectronics has introduced the ELDRIVE101-HPD reference board, which is designed to control 750-watt brushless direct current (BLDC) motors.
The board combines the STDrive101 triple half-bridge triple-phase gate driver with the Arm Cortex M0+ STM32G071KB microcontroller. Key features of the board include six 60V STL220N6F7 MOSFETs to drive BLDC motors, low power consumption in sleep mode and compact size. The board is designed for use in small battery-powered devices such as hair dryers, power tools and fans, as well as household robots and personal drones.
The ELDRIVE101-HPD board features a 32-bit STM32G071KB Arm Cortex M0+ microcontroller that operates at up to 64 MHz, has 36 Kbytes of SRAM and 128 Kbytes of Flash. The STDRIVE101 three-phase single-chip gate driver is three half-bridges and operates at voltages from 5.5V to 75V. The STL220N6F7 power MOSFETs are low-impedance and provide up to 750W of power. The board is also equipped with various monitoring and protection functions such as current sensing, overload protection and thermal shutdown, as well as Hall effect sensor and encoder connectors.
The ELDRIVE101-HPD board circuitry, including the microcontroller, gate driver and MOSFETs, is designed and supplied by STMicroelectronics. Users can download the Gerber files and bill of materials from the company's website. The X-CUBE-MCSDK STM32 software development kit for controlling BLDC motors is also available. The new board offers a turnkey solution for controlling high-power BLDC motors and can be used by OEMs in a variety of applications.
