STMicroelectronics EVLDRIVE101-HPD

Overview

EVLDRIVE101-HPD from STMicroelectronics is a circular, 50 mm diameter reference design board for three-phase brushless DC motor control, integrating the STDRIVE101 triple half-bridge gate driver, STM32G071KB Arm® Cortex®-M0+ MCU (128 KB Flash, 36 KB SRAM), and STL220N6F7 60 V/1.2 mΩ N-channel MOSFETs enabling up to 15 A RMS output current and 750 W power delivery in battery-powered systems.

For engineers reviewing the EVLDRIVE101-HPD datasheet, EVLDRIVE101-HPD pinout, EVLDRIVE101-HPD application, or EVLDRIVE101-HPD equivalent, this board supports FOC and trapezoidal control-both sensored (Hall/encoder) and sensorless (BEMF)-with integrated current sensing, thermal monitoring, UVLO, overcurrent protection via V_DS monitoring, and low-power standby triggered externally.

Technical Context

The board implements a complete three-phase inverter stack with tightly coupled control: the STM32G071KB executes real-time motor algorithms while directly managing STDRIVE101's INH/INL inputs and fault reporting via nFAULT. BEMF sensing and shunt-based current feedback (PA0/PA1/PA2) feed into the MCU's ADC for closed-loop commutation.

Power conversion uses L7983 (5 V buck) and LDL112 (3.3 V LDO) to supply MCU, gate drivers, and analog circuitry; the STL220N6F7 MOSFETs operate in synchronous six-step or PWM-driven half-bridge configurations with bootstrap gate drive (BOOT1–BOOT3) and dedicated high-side (GHS1–GHS3) and low-side (GLS1–GLS3) terminals.

FAQ

What motor control techniques does EVLDRIVE101-HPD support?

EVLDRIVE101-HPD supports both field-oriented control (FOC) and trapezoidal (six-step) commutation, with configurable support for Hall-effect sensors, quadrature encoders, and sensorless BEMF detection. The STM32G071KB's hardware-accelerated timers and ADC trigger sequencing enable precise timing alignment between PWM generation and current sampling.

How is overcurrent protection implemented on this board?

Overcurrent protection uses two independent methods: (1) shunt resistor sensing (SNSU_P/SNSV_P/SNSW_P) feeding into TSV991 op-amps and the MCU's ADC for software-based current limiting, and (2) real-time V_DS monitoring of STL220N6F7 MOSFETs via STDRIVE101's internal comparator for hardware-fast shutdown (< 1 µs response).

Can EVLDRIVE101-HPD operate from a single-cell Li-ion battery?

No - the minimum operating voltage is 18 V, corresponding to at least a 5S Li-ion pack (nominal 18.5 V). The L7983 and LDL112 regulators require sufficient headroom; operation below 18 V triggers UVLO and disables the power stage.

Is external programming hardware required to use this board?

No - the board includes an STDC14 SWD connector for debugging and programming, and supports direct firmware updates over UART using the onboard USART_TX/USART_RX lines. No separate ST-LINK is needed for basic flashing or serial communication.
