STSPIN32G0251QTR

Overview

The STSPIN32G0251QTR is a system-in-package integrating an STM32G031x8x3 microcontroller and a 250 V triple half-bridge gate driver. The MCU features a 32-bit ARM Cortex-M0+ core operating up to 64 MHz, equipped with 64 KB flash memory, 8 KB SRAM, and a 12-bit ADC. The gate driver supports N-channel MOSFETs or IGBTs with a high-voltage rail up to 250 V, ±50 V/ns dV/dt immunity, and source/sink currents of 200 mA / 350 mA at 25 °C. It includes SmartSD overcurrent protection, UVLO, interlocking, and deadtime functions.

Feature Summary

• Integrated 250 V triple half-bridge gate driver with ±50 V/ns transient immunity
• ARM Cortex-M0+ MCU core running up to 64 MHz with 64 KB Flash and 8 KB SRAM
• SmartSD comparator for fast overload and overcurrent protection
• Built-in bootstrap diodes, UVLO, interlocking, and deadtime functions

Applications

• Three-phase motor drivers
• Inverters
• Industrial appliances and fans

Procurement Notes

Verify the QFN 10x10 72L pitch 0.5 package configuration and ensure compatibility with the required voltage levels. Confirm that the embedded STM32 firmware meets specific application requirements before integration.

Selection Notes

Select this component for applications requiring integrated control and power stages in a compact form factor. Ensure the external power supply provides stable VCC between 9 V and 20 V and VDD between 1.7 V and 3.6 V for reliable operation.

Part Context

This device belongs to the STSPIN32G series, designed for three-phase BLDC motor control. It combines the processing capabilities of the STM32G0 family with high-voltage power stage integration to reduce PCB area and component count.

Replacement Considerations

Direct replacements within the same package and pinout are limited. Consider the STSPIN32G0252 for higher current drive capability (1 A/0.85 A) if load requirements exceed the 200 mA/350 mA limits of the STSPIN32G0251.
