Vds at that point is then governed by Ohm’s law To participate you need to register. Thanks for your explanation. Lrf9130 the mosfet as a non-linear voltage controlled resistor. At the same time, I D will increase sharply until 3. This is the one I use because it has a fast Switching time, and low Gate Resistance. Couldn’t find the model that I am using in there. Hero Banned Mar 8, How do I interpret these data.?

How about the VGSS.? Does it means that my gate voltage cannot exceed -5V.? There are lots of “flying capacitor boost” type circuits that do this google it. MrNobody New Member Mar 16, MrNobody New Member Mar 5, If that is the case then the power loss would be too much Forums New posts Search forums. MrNobody New Member Mar 4, Just saying hello Started by MichaelaJoy Yesterday at 6: Lets say, the Drain is connected to the supply of 60V.


What’s the value of R1? Here is a simulation of the H-Bridge circuit. Yes, it would blow up irrf9130 there is no resistance at the Gate So if you had an incomming signal that was either 1 or a 0, High or Low, only 1 N and 1 P type mosfet will turn on, datsaheet if you refer to the diagram, the MOSFETS that turn on will be diagonal from each other.

According to the simulation, the V DS of Q1 and Q4 is too large and only less than half of the voltage fall across R1. The resistance R DS at that time would be somewhere near mOhm 0.

Hero Banned Mar 4, I could be wrong – I was once before. Roff Well-Known Member Mar 15, Due to the lag in the Logic Gates. I think I am getting there. Is that what you have been trying to say Hero? Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at This way, when power is off, any noise or watever will not damage your motor, Or if the signal is somehow borken or not getting thru, the H-Bridge simply wont turn on.

When you say “source flowing at about 5 to 10V”. The resistance is some function of the gate-source – for a given Vgs, the mosfet will act like a very small value resistor, up to some current limit when it enters saturationand starts acting like a current source and dissipating a lot of power. For fast switching times, you want to be able to discharge the input capacitance as quickly as possible; you can buy special driver ICs for this.


Too much power loss and too little power reach the motor.

Hero Banned Mar 5, Correct – In order datssheet use a n-mosfets on the high side, you need to supply a gate voltage that is greater than the supply voltage that it is switching – since you want Vs of the mosfet to be very close to the supply voltage.

H-Bridge DC motor driver

In order to do this, I need alot of gate voltage. N-mosfets are inherently cheaper and better, hence most high power drivers end up using all N-mosfets. Articles Top Articles Search resources. Did anyone datashset look at the specs on those parts? I knew there was something I had missed. Hero Banned Mar 16, H-Bridge DC motor driver.
