Fairchild公司的FNA21012A是Motion SPM® 2模塊,提供用于交流馬達,BLDC和永磁馬達(PMSM)的全特性高性能的1200V/10A三相反相輸出級,包括內置IGBT的柵極驅動器,多種模塊保護特性如欠壓鎖住,過流關斷,溫度檢測和故障報告.主要用于工業AC 400V級的工業馬達運動控制.本文介紹了FNA21012A主要特性, 框圖, 開關測試電路以及FNA21012A 1200V參考設計主要特性, 空調器室外風扇馬達驅動框圖, 三相逆變器參考設計和PCB布局圖.
The FNA21012A is a Motion SPM® 2 module providing a fully-featured, high-performance inverter output stage for AC induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features: under-voltage lockouts, over-current shutdown, temperature sensing, and fault reporting. The built-in, high-speed HVIC requires only a single supply voltage and translates the incoming logic level gate inputs to high-voltage, high-current drive signals to properly drive the module’s internal IGBTs.
Separate negative IGBT terminals are available for each phase to support the widest variety of control algorithms.
FNA21012A主要特性:
• UL Certified No. E209204 (UL1557)
• 1200 V - 10 A 3-Phase IGBT Inverter, Including Control ICs for Gate Drive and Protections
• Low-Loss, Short-Circuit-Rated IGBTs
• Very Low Thermal Resistance Using Al2O3 DBC Substrate
• Built-In Bootstrap Diodes and Dedicated Vs Pins Simplify PCB Layout
• Separate Open-Emitter Pins from Low-Side IGBTs for Three-Phase Current Sensing
• Single-Grounded Power Supply Supported
• Built-In NTC Thermistor for Temperature Monitoring and Management
• Adjustable Over-Current Protection via Integrated Sense-IGBTs
• Isolation Rating of 2500 Vrms / 1 min.
FNA21012A應用:
• Motion Control - Industrial Motor (AC 400 V Class)
