STSPIN32F0251TR

Overview

The STSPIN32F0251TR is a system-in-package integrating an STM32F031x6 MCU and a triple half-bridge gate driver for three-phase BLDC motor control. 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 embedded ARM Cortex-M0 core operates at 48 MHz with 32 kB Flash and 4 kB SRAM. Driver current capability is 200 mA source and 350 mA sink. Operating voltage ranges from 9 V to 20 V, with an extended temperature range of -40 °C to +125 °C.

Feature Summary

• Integrated 250 V triple half-bridge gate driver with 200/350 mA source/sink current
• ARM Cortex-M0 MCU (STM32F031) with 48 MHz clock, 32 kB Flash, and 4 kB SRAM
• SmartSD comparator for fast overcurrent protection with programmable disable time
• Built-in bootstrap diodes, interlocking, deadtime, and UVLO protection

Applications

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

Procurement Notes

Verify the 'TR' suffix indicates tape and reel packaging. Confirm the specific revision level against the latest official datasheet DS13048 Rev 4. Ensure compatibility with the required PCB footprint for the TQFP 10x10 64L package.

Selection Notes

Select this model for applications requiring up to 250 V bus voltage and moderate gate drive currents (200 mA source). Compare with STSPIN32F0252 if higher peak currents (1 A source) are needed. Ensure the application firmware utilizes the available 21 GPIOs and 10 ADC channels effectively.

Part Context

Part of the STSPIN32F025x family, which includes the STSPIN32F0252 variant offering higher drive currents. These devices share pinout compatibility within the 250 V class, facilitating hardware reuse across different power levels in the same product line.

Replacement Considerations

STSPIN32F0252 offers identical functionality with increased source/sink current capabilities (1 A / 0.85 A). Direct substitution requires verifying that the higher current rating does not necessitate changes to external component stress ratings.
