Many designers have adopted a strategy that uses a power MOSFET as a diode and controls the voltage drop across it. The integrated circuit (IC) that serves this role has been dubbed an Ideal Diode ...

PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) has announced an ideal diode controller for system protection against reverse discharge. Emulating an ideal diode ...

(Source: Quora) To understand the ideal-diode operation, we can use the Analog Devices LTC4358 as an example (Fig. 4). This 12-V/5-A IC contains an internal 20-mΩ MOSFET as the pass element and ...

So, while a real diode will only pass current in one direction, it will also drop some of the voltage. [Julian] shows you how you can get simulated ideal diodes and why you might want them in a ...

AOS’s new family of ideal diode-based protection switches offer a robust, reliable solution. And as always, AOS’s ability to combine TrenchFET technology with leading IC design enables a ...

For vehicle functional-safety applications, STMicroelectronics has combined hot-swap, soft-start and ideal-diode OR-ing in an IC intended to work with a pair of external n-channel mosfets over 4 to ...

smart ideal-diode controllers that drive external N-channel MOSFETs (NFETs) have been developed. The NFET must be placed on the high side; the smart diode controller IC also takes power from the ...

An Ideal diode is a circuit that “makes a FET act like a diode.” Although somewhat more complex than a simple diode, the ideal diode can significantly improve system efficiency and consume less power ...

Rbias determines the turn-on speed of the MOSFET. When the ideal diode circuit is turning on, the internal transistor is held off by the drain diode and the MOSFET voltage drops. Rbias pulls the gate ...

What if your Gigabit Ethernet protection circuit response resembled that of an ideal diode? Asks Len Stencel, applications manager for semiconductor products at Bourns. Gigabit Ethernet (GbE) is a ...
