STSPIN32F0251

Application Specific Microcontrollers Overview

The STSPIN32F0251 is a system-in-package integrating an STM32F031x6 MCU and a triple half-bridge gate driver for three-phase applications. It supports N-channel MOSFETs or IGBTs with a high-voltage rail up to 250 V and dV/dt immunity of ±50 V/ns. The MCU features a 32-bit ARM Cortex-M0 core running at 48 MHz, 32 kB Flash, and 4 kB SRAM. Driver current capability is 200 mA source and 350 mA sink. Operating temperature ranges from -40 °C to +125 °C.

Application Specific Microcontrollers Feature Summary

• Integrated 250 V triple half-bridge gate driver with integrated bootstrap diodes
• ARM Cortex-M0 MCU with 48 MHz clock, 32 kB Flash, and 4 kB SRAM
• SmartSD comparator for fast overcurrent protection with programmable disable time
• Interlocking, deadtime (200–400 ns), and UVLO functions prevent cross-conduction

Application Specific Microcontrollers Applications

• Home and industrial refrigerator compressors
• Industrial drives, pumps, and fans
• Air conditioning compressors and fans
• Corded power tools and garden tools
• Home appliances and industrial automation

Application Specific Microcontrollers Procurement Notes

Verify the specific package variant required, as the device is available in TQFP 10x10 64L pitch 0.5 and QFN 10x10 72L pitch 0.5. Confirm that the selected part number corresponds to the STSPIN32F0251/Q suffix for the correct driver current ratings. Ensure environmental compliance requirements match the Ecopack2 standard.

Application Specific Microcontrollers Selection Notes

Select the STSPIN32F0251 when lower peak drive currents are sufficient, specifically 200 mA source and 350 mA sink. If higher drive strength is needed, consider the STSPIN32F0252 which offers 1 A source and 0.85 A sink. Ensure the application voltage does not exceed the 250 V rail limit and that the PCB layout accommodates the thermal resistance characteristics of the chosen package.

Application Specific Microcontrollers Part Context

This component belongs to the STSPIN32F025x series, which includes the STSPIN32F0251 and STSPIN32F0252 variants. These devices are designed as highly integrated solutions to reduce PCB area and bill of materials for three-phase motor control applications by combining the microcontroller and power stage in a single package.

Application Specific Microcontrollers Replacement Considerations

The STSPIN32F0252 is a direct functional alternative within the same family but provides different driver current capabilities (1 A source / 0.85 A sink). Verify pin compatibility and thermal performance if substituting between packages.
