Is this charging current high enough to damage the MCU pin? I don’t see in the specifications where 5V is given as a minimum.

It’s like just passing above the threshold voltage on a BJT. Mark 1, 7 36 The data sheets can be misleading, they often give the gate voltage for mA current on the front page, and you find that they need 12V for 5A, say. The reason they include it at all is that the relative behavior current goes up with increasing gate voltage and increasing drain voltage is universal Will this be sufficient?

Any lower than that, and you have no guarantees whatsoever of device behavior beyond the uA current of the Vgs threshold. MCU pins are usually inputs on reset, and this could cause the gate to float momentarily, perhaps turning the device on, until the program starts running.

It’s not cheap 0. In other words, drive past that value. I understand that the gate of the MOSFET behaves like a capacitor, and therefore draws some current while “charging”, and then dtasheet thereafter. Home Questions Tags Users Unanswered.

Email Required, but never shown. You only pay power to switch a MOSFET, not to keep it datasheef, which reduces power dissipation in itfz14 the transistor and the part that drives it, especially if switching is infrequent.

Is this “saturation” achieved by simply providing a high enough voltage on the base that the MOSFET is completely “on”? The resistor from MCU pin to gate is also used to slow down the switching edge, to reduce ringing, overshoot, and EMI. The FQP30N06L is designed to be driven from voltages of at least 5V, which is the minimum voltage that they specify on-resistance. If the VGS threshold is like 1.

By datashet a resistor in series with the gate, I can protect the pin, but this will slow down the switch, possibly resulting in high heat dissipation by the MOSFET? Therefore, Raspberry Pi’s 3. But you really need a gate daasheet circuit from 3. Sign up using Email and Password. The downside is that a MOSFET doesn’t pull a constant amount of current across the entire edge, since it looks like a resistor; this slows down switching a capacitive load. I have a few questions, however.

All of that said, I see that a lot of people still recommend using an opto-isolator between the micro-controller and the MOSFET, just to be extra safe.

I’d put two resistors into the circuit: Sign up using Darasheet.

IR non logic level vs. Alastair McCormack 3. Note that “logic level” does not seem to be an exactly standardized term, and it won’t necessarily show up as datsheet parameter in the parametric search at the vendor sites, nor will it necessarily show up in the data sheet.

More discussion on this blog entry.

I’ve generally done the opposite: Don’t drive this directly from an MCU. More seriously, just because 3. Hi JasonS, forgive my ignorance.

In other words, it’s the mean behavior, not the extreme, and you can’t rely on it being valid for all devices. The big thing is to look in the data sheet and check the VGS threshold value and look at the graph that shows current flow vs VGS.

As far as protection What number am I looking for to determine whether 3. There are some datqsheet logic-level inputs, though.

Instead, look at the datasheets and the rated on-resistance Rdson, which is specified at a certain gate-source voltage for each part. The MOSFET isn’t considered “on” until the device has completely resistive behavior over a specified range of currents. Post as a guest Name.
