The 250V STSPIN32F0251 and STSPIN32F0252, and 600V STSPIN32F0601 and STSPIN32F0602 combine three-phase gate drivers and an STM32F0 Arm® Cortex®-M0 microcontroller to simplify high-voltage Brushless DC (BLDC) motor drives.

The STSPIN32F025x system-in-package is an extremely integrated solution for driving three phase applications, helping designers to reduce PCB area and overall bill-of-material.

It embeds an STM32F031x6x7 featuring an ARM® 32-bit Cortex®-M0 CPU and a 250 V triple half-bridge gate driver, able to drive N-channel power MOSFETs or IGBTs.A comparator featuring advanced smartSD function is integrated, ensuring fast and effective protection against overload and overcurrent.

The high-voltage bootstrap diodes are also integrated, as well as anti cross-conduction,
deadtime and UVLO protection on both the lower and upper driving sections, which prevents the power switches from operating in low efficiency or dangerous conditions. Matched delays between low and high-side sections guarantee no cycle distortion.

The integrated MCU allows performing FOC, 6-step sensorless and other advanced driving algorithms including the speed control loop.

评估板EVSPIN32F0251S1: 3-phase inverter based on STSPIN32F0251

The EVSPIN32F0251S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller, which embeds a 3‑phase 250 V gate driver and a Cortex®‑M0 STM32 MCU. The power stage features STD17NF25 MOS, but can be populated with any IGBT or Power MOSFET in DPAK or powerFLAT 6x5 HV package.

The board has a single-shunt sensing topology, and both the field-oriented control (FOC) and sensored or sensorless 6‑step control can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.It provides an easy-to-use solution for the evaluation of the device in different applications such as battery operated tools, industrial pumps, fans and home appliances.

The evaluation board is compatible with a wide range of input voltage and includes a power supply stage with the VIPER013BLS in buck configuration to generate +15 V and +3.3 V supply voltages required by the application.

Debug and configuration of FW can be performed with standard STM32 tools through the detachable ST-LINK debugger. SWD and UART TX RX connectors are also available.
