Fairchild公司的FNA21012A是Motion SPM® 2模块,提供用于交流马达,BLDC和永磁马达(PMSM)的全特性高性能的1200V/10A三相反相输出级,包括内置IGBT的栅极驱动器,多种模块保护特性如欠压锁住,过流关断,温度检测和故障报告.主要用于工业AC 400V级的工业马达运动控制.本文介绍了FNA21012A主要特性, 框图, 开关测试电路以及FNA21012A 1200V参考设计主要特性, 空调器室外风扇马达驱动框图, 三相逆变器参考设计和PCB布局图.
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..
