NCV68261是一款反极性保护和理想二极体NMOS控制器,具有可选的高端开关功能,旨在作为功率整流二极体和机械功率开关的更低损耗和更低正向电压的替代品。此控制器与一个或两个N通道MOSFET配合运行,以实现低功耗,并根据Source to Drain差分电压极性来控制外部NMOS的开启或关闭行为状态。根据汲极引脚连接,理想二极体和高端...
A circuit configuration produces an at least approximately ideal diode characteristic on the basis of a diode. A power MOSFET has a control path connected in parallel with the diode, a load path forming connection terminals of the ideal diode, and a gate connection to which a predetermined ...
不可以，ideal diode controller本身不是二极管，它负责开断mos管实现多电源之间的切换，和buck电路中的...
Yes, think what happens if the right side is more positive than the left (ground is still zero). Mosfet will be on and current goes in reverse. Thus nit ideal diode, only reverse polarity protection. Logged The following users thanked this post: LooseJunkHaterMK14 Super Contributor Posts: ...
The MOSFET is placed in the direction where its intrinsic body diode is in the same direction of the diode function to mimic (top). When VA is higher than VC, the current can naturally flow from left to right through the intrinsic diode. The control circuit turns on the MOSFET to reduce...

The MP9989 fromMonolithic Power Systems, Inc. is a fast turn-off, intelligent rectifier for flyback converters that integrates a 100V MOSFET. It can replace a diode rectifier for higher efficiency and power density. The chip regulates the forward voltage drop of t...
Ideal Diode Controllers In the power domain high efficiency is critical. Power losses must be minimized. Many manufacturers have adopted a strategy that uses a power MOSFET as a diode and controls the voltage drop across it. The integrated circuit that serves this function ...
Figure 1 shows a simple 12V/15A ideal diode-OR application. An MBR1635 Schottky diode would dissipate 8W in this circuit. In contrast, the HAT2165 3.4mΩ MOSFET drops 15A • 3.4mΩ = 51mV and dissipates only 51mV • 15A = 0.765W. The result is a drastic reduction in PCB ...
