STSPIN32F0252Q

Application Specific Microcontrollers Overview

The STSPIN32F0252Q is a system-in-package integrating an STM32F031 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 1 A source and 0.85 A sink peak currents. Operating voltage ranges from 9 V to 20 V, with an extended temperature range of -40 °C to +125 °C.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'Q' corresponds to the QFN 10x10 72L package variant when sourcing. Confirm that the ordering information matches the required creepage distance of 1.8 mm associated with this package type. Ensure the component grade meets industrial requirements as specified in the datasheet documentation.

Application Specific Microcontrollers Selection Notes

Select the STSPIN32F0252/Q variant specifically for applications requiring higher driver peak currents (1 A source / 0.85 A sink) compared to the STSPIN32F0251. This model is suitable for driving larger N-channel MOSFETs or IGBTs. Ensure the application voltage does not exceed the 250 V rail limit and that the logic inputs are compatible with the 3.3 V MCU supply levels.

Application Specific Microcontrollers Part Context

This component belongs to the STSPIN32F025x series, which provides advanced BLDC control solutions with embedded microcontrollers. The 'Q' suffix typically denotes the QFN package option, offering a smaller footprint and higher thermal performance compared to the TQFP variant. It serves as a highly integrated alternative to discrete driver and MCU combinations.

Application Specific Microcontrollers Replacement Considerations

The STSPIN32F0251/Q is a direct pin-compatible alternative within the same family but offers lower driver current capabilities (200 mA source / 350 mA sink). Designers must verify if the reduced current capacity meets the gate charge requirements of their specific power switches.
