Don’t drive this directly from an MCU. As far as protection Post as a guest Name. Sign up using Email and Password. Will lrfz14 be sufficient? I understand that the gate of the MOSFET behaves like irfx14 capacitor, and therefore draws some current while “charging”, and then none thereafter. The resistor from MCU pin to gate is also used to slow down the switching edge, to reduce ringing, overshoot, and EMI.

More discussion on this blog entry. More seriously, just because 3.

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.

It’s not cheap 0.

Some devices may have quite a bit higher Rdson at 3. By placing a resistor in series with the gate, I can protect the pin, but datashret will slow down the switch, possibly resulting in high heat dissipation by the MOSFET? Email Required, but never shown. If the VGS threshold is like 1.

I don’t see in the specifications where 5V is given as a minimum. Is this “saturation” achieved by simply providing a high enough voltage on the base that the MOSFET is completely “on”?

irf14 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. 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.

Any lower than that, and you have no guarantees whatsoever of device behavior beyond the uA current of the Vgs threshold. You only irfs14 power to switch a MOSFET, not to keep it on, which reduces power dissipation in both the transistor and the part that drives it, especially if switching is infrequent.

The FQP30N06L is designed to be driven from voltages of at least 5V, which is the minimum datazheet that they specify on-resistance. The reason they include it at all is that the datssheet behavior current goes up with increasing gate voltage and increasing drain voltage is universal IR non logic level vs. In other words, it’s the mean behavior, not the extreme, and you can’t rely on it being valid for all devices.

Note that “logic level” does not seem to be an exactly standardized term, and it won’t necessarily show up as a parameter in the parametric search at the vendor sites, nor will it necessarily show up in the data sheet. Mark 1, 7 36 The MOSFET isn’t considered “on” until the device has completely resistive behavior dataeheet a specified range of currents. Is this charging current high enough to damage the MCU pin?

Instead, look at the datasheets and the rated on-resistance Rdson, which is specified at a certain gate-source voltage for each part. 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 like just passing above the threshold voltage on a BJT.

I’d put two resistors into the circuit:
