Power Integrations公司今日发布BridgeSwitch™集成半桥电路(IHB)的电机驱动器IC产品系列。BridgeSwitch IC内部集成了两个性能加强的FREDFET（具有快恢复外延型二极管的场效应晶体管）分别用于半桥电路的上管和下管，且具有无损耗的电流检测功能，可使300 W以内的无刷直流(BLDC)电机驱动器应用中的逆变器转换效率达到98.5%。
IHB驱动器所提供的优异效率和分布式散热方法可省去散热片，有助于降低系统成本和重量。由于具有集成无损耗电流检测、总线电压检测和系统级过温检测等特性，因此该器件系列非常适合家电中的BLDC电机驱动应用。BridgeSwitch器件适合冰箱压缩机、暖通空调系统风扇以及其他家用和轻型商用泵、风扇和风机。
