STSPIN32F0601QTR

Overview

The STSPIN32F0601QTR is a system-in-package integrating an STM32F031 ARM Cortex-M0 microcontroller with a 600 V triple half-bridge gate driver. It drives N-channel MOSFETs or IGBTs for three-phase applications. The MCU operates up to 48 MHz with 32 kB Flash and 4 kB SRAM. The gate driver supports 9 V to 20 V logic, providing 200 mA source and 350 mA sink peak currents. Key features include integrated bootstrap diodes, SmartSD overcurrent protection, UVLO, interlocking, and deadtime functions.

Feature Summary

• Integrated 600 V triple half-bridge gate driver with ±50 V/ns dV/dt immunity
• STM32F031 MCU with ARM Cortex-M0 core running at 48 MHz
• SmartSD comparator for fast overload and overcurrent protection
• Built-in bootstrap diodes, UVLO, interlocking, and deadtime generation

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 the Q suffix indicates tape-and-reel packaging when ordering. Confirm the specific package variant (TQFP or QFN) matches the design requirements. Check for RoHS compliance and lead-free status in official documentation before procurement.

Selection Notes

Select this component for high-voltage three-phase motor control requiring integrated MCU processing. Ensure the application voltage does not exceed 600 V. Verify that the 200/350 mA drive current meets the external MOSFET or IGBT gate charge requirements at the target switching frequency.

Part Context

This part belongs to the STSPIN32F060x family, which includes variants like the STSPIN32F0602 offering higher drive currents. The QTR suffix denotes the QFN package in tape-and-reel format, suitable for automated surface-mount assembly processes.

Replacement Considerations

The STSPIN32F0602 offers identical MCU integration but provides 1 A source and 0.85 A sink currents. Verify pin compatibility and thermal performance if substituting for higher load requirements.

FAQ

How does the SmartSD function protect against overcurrent?

The internal comparator monitors the CIN pin. If the voltage exceeds the reference threshold and persists longer than the filter time, it triggers immediate shutdown of all driver outputs and signals the FAULT pin.

What is the maximum switching frequency supported?

The device supports a maximum switching frequency of 800 kHz, though actual limits depend on power dissipation and thermal conditions.

How are unused GPIO pins handled?

Unused GPIOs inside the SiP should be configured as output low level by software after startup to prevent floating inputs and unnecessary power consumption.
