STSPIN32F0252TR

Overview

The STSPIN32F0252TR is a system-in-package (SiP) integrating an STM32F031x6 microcontroller and a triple half-bridge gate driver. It features a 32-bit ARM Cortex-M0 core operating up to 48 MHz with 32 kB Flash and 4 kB SRAM. The embedded gate driver supports N-channel MOSFETs or IGBTs with a high-voltage rail up to 250 V, providing 1 A source and 0.85 A sink peak currents. Key electrical parameters include a dV/dt immunity of ±50 V/ns, a gate driving voltage range of 9 V to 20 V, and an extended operating temperature range from -40 °C to +125 °C.

Feature Summary

• Integrated 250 V triple half-bridge gate driver capable of driving N-channel power MOSFETs or IGBTs
• Embedded STM32F031 MCU with ARM Cortex-M0 core, 32 kB Flash, and 4 kB SRAM
• SmartShutDown comparator for fast overcurrent protection with programmable disable time
• Built-in interlocking, deadtime, UVLO, and matched propagation delay functions

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 systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with the required PCB footprint and thermal management strategy. Confirm that the firmware loaded into the embedded MCU meets the application's control algorithm requirements before procurement.

Selection Notes

Select the STSPIN32F0252 variant specifically when higher drive current capability (1 A source / 0.85 A sink) is required compared to the STSPIN32F0251. Ensure the external bootstrap diodes and capacitors are rated for the target switching frequency and voltage levels. Verify that the input logic signals align with the MCU's 3.3 V or 5 V tolerant I/O specifications.

Part Context

This component belongs to the STSPIN32F025x series, which provides highly integrated solutions for three-phase BLDC motor control. It combines the processing power of the STM32F031 family with robust power stage capabilities in a single package to reduce PCB area and bill of materials.

Replacement Considerations

The STSPIN32F0251 offers similar integration but with lower drive currents (200 mA source / 350 mA sink). The STSPIN32F0A is a different generation with distinct pinouts and performance characteristics. Direct pin-to-pin replacement requires verifying current ratings and firmware compatibility.
