STSPIN32F0252

Overview

The STSPIN32F0252 is a system-in-package integrating an STM32F031x6 MCU and a triple half-bridge gate driver for three-phase BLDC motor control. 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 and dV/dt immunity of ±50 V/ns. Driver current capability is 1 A source and 0.85 A sink peak current. Operating conditions include a VCC range of 9 V to 20 V, an extended temperature range from -40 °C to +125 °C, and packages including TQFP 10x10 64L and QFN 10x10 72L.

Feature Summary

• Integrated 250 V triple half-bridge gate driver with 1 A source / 0.85 A sink peak current capability
• Embedded STM32F031x6 MCU with ARM Cortex-M0 core, 32 kB Flash, and 4 kB SRAM
• SmartShutDown (SmartSD) comparator for fast overcurrent protection with programmable disable time
• Built-in interlocking, deadtime, UVLO, and matched propagation delays for cycle distortion prevention

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

Procurement Notes

Verify package availability as the component is offered in both TQFP 10x10 64L and QFN 10x10 72L configurations. Confirm specific ordering suffixes required for the desired footprint. Ensure compliance with humidity sensitivity handling procedures during storage and assembly. Check for RoHS and Ecopack2 compliance status prior to procurement.

Selection Notes

Select the STSPIN32F0252 when higher gate drive current is required compared to the STSPIN32F0251 variant. The device supports Field-Oriented Control (FOC), 6-step sensorless, and speed control algorithms via the integrated MCU. Ensure external components support the 9 V to 20 V VCC supply range and that PCB layout accommodates the exposed pad for thermal dissipation.

Part Context

This component belongs to the STSPIN32F0 series of advanced BLDC controllers. It shares architectural similarities with the STSPIN32F0 but offers enhanced voltage ratings and driver currents. The STSPIN32F0252 specifically provides higher source/sink currents than the STSPIN32F0251, making it suitable for driving larger power stages while maintaining the same embedded MCU capabilities.

Replacement Considerations

The STSPIN32F0251/Q serves as a lower-current alternative within the same family. Direct pin-compatible substitutes may exist within the broader STSPIN32F0 series, but verification of driver current specifications and package dimensions is necessary before substitution.
