STSPIN32G0252QTR

Overview

The STSPIN32G0252 is a system-in-package integrating an STM32G031x8 MCU and a three-phase gate driver. The MCU features a 32-bit ARM Cortex-M0+ core operating up to 64 MHz, with 64 Kbytes of flash and 8 Kbytes of SRAM. The gate driver supports high-voltage rails up to 250 V, providing 1.0 A source and 0.85 A sink currents at 25 °C. It includes integrated bootstrap diodes, UVLO, interlocking, deadtime, and SmartSD overcurrent protection. The device operates in an extended temperature range from -40 °C to +125 °C within a QFN 10x10 72L package.

• SmartSD comparator for fast overcurrent protection with configurable disable time via OD pin
• Built-in protections including UVLO, interlocking, deadtime, and matched propagation delays

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet DS14509 to confirm package type and temperature grade. Ensure compatibility with the QFN 10x10 72L pitch 0.5 footprint during PCB layout. Confirm that the selected variant meets the required thermal resistance and electrical specifications for the target application environment.

Selection Notes

Select this component for applications requiring integrated sensorless or sensored FOC control with high-voltage isolation. The 12-bit ADC and dedicated motor control timers support precise current sensing and PWM generation. Ensure the external MOSFETs are compatible with the 9 V to 20 V gate driving voltage range and the 1.0 A/0.85 A drive capability.

Part Context

This part belongs to the STSPIN32G series of intelligent power switches designed for three-phase BLDC motor control. It combines the processing power of the STM32G0 microcontroller family with high-voltage analog drivers, reducing component count and board space compared to discrete solutions.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the verified documentation. Evaluate alternatives based on matching pinout, voltage ratings (250 V), and MCU architecture (ARM Cortex-M0+) if cross-referencing is required.
