STSPIN32G0252Q

Overview

The STSPIN32G0252Q is a system-in-package integrating an STM32G031x8x3 microcontroller and a 250 V triple half-bridge gate driver. The MCU features an 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 source/sink currents of 1.0 A / 0.85 A at 25 °C. It includes integrated bootstrap diodes, SmartSD overcurrent protection, UVLO, interlocking, and deadtime functions. The device operates within an extended temperature range of -40 °C to +125 °C.

• Advanced SmartSD comparator for fast overload and overcurrent protection
• Built-in high-voltage bootstrap diodes, UVLO, interlocking, and deadtime logic

Applications

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

Procurement Notes

Verify the specific ordering suffix 'Q' against official documentation to confirm if it denotes automotive grade qualification or specific packaging variations. Ensure compatibility with QFN 10x10 72L packages requiring 1.8 mm creepage distance. Confirm availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component for applications requiring high-voltage three-phase control with integrated processing. The 250 V rating suits industrial motors, while the embedded MCU simplifies FOC implementation. Consider thermal resistance (22.4 °C/W) and power dissipation limits when designing PCB layouts for continuous operation.

Part Context

This part belongs to the STSPIN32G0 series, which combines general-purpose STM32 MCUs with three-phase gate drivers. The G0252 variant specifically targets 250 V applications, offering higher drive current compared to lower-rated siblings like the G0251. It serves as a complete solution for reducing BOM and PCB area in BLDC motor control systems.

Replacement Considerations

Direct replacements within the same family include STSPIN32G0251, though it offers lower drive current (200/350 mA). For higher performance needs, consider the STSPIN32G4 series with Cortex-M4 cores. Verify pinout and voltage ratings before substituting.
