STMicroelectronics EVLPWD-FAN-PUMP

Overview

EVLPWD-FAN-PUMP from STMicroelectronics is a compact 3-phase inverter evaluation board designed for fan and pump motor control applications, integrating the PWD5T60 high-voltage power stage (500 V BVDSS, 1.38 Ω RDS(on)), STM32G071RBT6 Arm® Cortex®-M0+ MCU (128 KB Flash, 36 KB RAM), and VIPER011LS AC/DC converter. It supports both 6-step and field-oriented control (FOC) of BLDC and PMSM motors up to 100 W, with adjustable overcurrent protection (1.8 Apeak) and bus voltage sensing.

For engineers reviewing the EVLPWD-FAN-PUMP datasheet, EVLPWD-FAN-PUMP pinout, EVLPWD-FAN-PUMP application, or EVLPWD-FAN-PUMP equivalent, this board serves as a plug-and-play reference design for rapid validation of high-voltage motor drive firmware, current sensing topologies (single/three-shunt), thermal and overvoltage protection schemes, and real-time speed regulation via potentiometer or digital interface.

Technical Context

The board implements a complete motor control signal chain: the STM32G071RBT6 executes FOC or 6-step algorithms using ADC-sampled shunt currents (CSEN_U/V/W), BEMF networks, and Hall/encoder inputs, while the PWD5T60 provides integrated gate driving and cycle-by-cycle hardware current limiting. The VIPER011LS generates isolated 12 V and 3.3 V supplies from wide-range AC/DC input (15–280 VAC / 20–400 VDC).

Protection is implemented at multiple levels: hardware overcurrent detection (1.8 Apeak threshold), thermal shutdown via NTC sensor, undervoltage/overvoltage lockout on VCC and bus rails, and fault reporting through the PWD5T60 FAULT pin routed to the MCU. All high-voltage sections are non-isolated - direct mains connection requires strict safety compliance.

FAQ

Is EVLPWD-FAN-PUMP certified for CE or UL compliance?

No - the EVLPWD-FAN-PUMP is an evaluation board intended solely for lab-based development and demonstration. It lacks full safety certification (e.g., CE, UL, IEC 61800-5-1) due to its non-isolated high-voltage topology and absence of enclosure, interlocks, or certified creepage/clearance. Users must integrate it into a certified end-product system meeting applicable regional safety standards.

Can the board drive motors beyond 100 W?

Not continuously - the 100 W rating reflects thermal limits under standard lab conditions (25°C ambient, no forced airflow). Sustained operation above this level risks MOSFET overheating, gate driver saturation, or capacitor derating. Short-term peak loads may be possible with active cooling and reduced duty cycle, but require custom thermal validation per IEC 60085.

What debug interfaces does the board support?

The board features a standard SWD (Serial Wire Debug) port compatible with STLINK/V2 or STLINK/V3 debuggers. No JTAG header is present. Firmware programming and real-time debugging (breakpoints, register inspection, memory access) are fully supported via STM32CubeIDE or Keil MDK using the SWDIO and SWCLK pins routed to J2.

Does the board include Hall sensor or encoder hardware?

Yes - it provides dedicated connectors (J5) and signal conditioning circuitry for digital Hall effect sensors (A/B/C channels) and quadrature encoder inputs. The STM32G071RBT6 GPIOs PA0–PA2 are configured as Hall inputs, while PC14 serves as encoder index (Z) input, all with ESD protection and pull-up resistors per ST's motor control reference design guidelines.
