十二种新型的Little Foot MOSFET系列产品据称是业界首批工作电压低到1.8V的功率MOSFET。由于解决了在低电压下负载切换的问题,这种P通道晶体管显然扫除了移动通信和计算应用中低系统电压的开发过程中所遇到的障碍。 根据生产厂家的介绍,这些器件还提供了在1.8、2.5和4.5V栅极电压下业界极低的接通电阻。例如Si4465DY,4.5V时R_(DS(on))=9mΩ,2.5V时为11 mΩ,1.8V时为16mΩ。这些值比现有的器件提高了35％。 MOSFET有单管和双管两种,其漏源电压的额定值为8V或12V。器件有8引
Twelve new Little Foot MOSFET families are said to be the industry’s first power MOSFETs to operate down to 1.8V. This P-channel transistor clearly eliminates the barriers encountered in the development of low-system voltages in mobile communications and computing applications by addressing the issue of load switching at low voltages. According to the manufacturer’s introduction, these devices also provide the industry’s lowest on-resistance at 1.8, 2.5 and 4.5V gate voltages. For example Si4465DY, R_ (DS (on)) = 9mΩ at 4.5V, 11mΩ at 2.5V and 16mΩ at 1.8V. These values are 35% more than existing devices. MOSFETs have one and two tubes, the drain-source voltage rating of 8V or 12V. The device has 8 leads
