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. Post as a guest Name. Email Required, but never shown. Orfz14 are some with logic-level inputs, though.

Any lower than that, and you have no guarantees whatsoever of device behavior beyond the uA current of the Vgs threshold. Hi JasonS, forgive my ignorance.

The resistor from MCU pin to gate is also used to slow down the switching edge, to reduce ringing, overshoot, and EMI. In other words, drive past that value. You only pay 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.

More seriously, just because 3. Datsaheet of that said, I see that a lot of people still recommend using an opto-isolator between the micro-controller datasheef the MOSFET, just to be extra safe. I’d put two resistors into the circuit: By orfz14 “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

I understand that the gate of the MOSFET behaves like a capacitor, and therefore draws some current while “charging”, and then none thereafter.

The downside is that a MOSFET doesn’t pull a constant amount of current across the entire edge, since datashewt looks like a resistor; this slows down switching a capacitive load.

I don’t see in the specifications where 5V is given as a minimum. Don’t drive this directly from an MCU. Sign up using Facebook. I’ve generally done the opposite: It’s like just passing above the threshold voltage on a BJT.

But you really need a gate driving circuit from 3. Home Questions Tags Users Unanswered. Sign up or log in Sign up using Google. By placing 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?

If the VGS threshold is like 1. 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. Will this be sufficient? Dataaheet far as protection In other words, it’s the mean behavior, not the extreme, and you can’t rely on it being valid for all devices.

IR non logic level vs. The MOSFET isn’t considered “on” until the device has completely resistive behavior over a specified range of currents. 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.

What number am I looking for to determine whether 3. Some devices may have quite a bit higher Rdson at 3. MCU pins are usually inputs on reset, and this could cause the gate to float momentarily, perhaps datasgeet the device on, until the program starts running.

Is this charging current high enough to damage the MCU pin? 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 Is this “saturation” achieved by simply providing a high enough voltage on the base that the MOSFET is completely “on”?

Therefore, Raspberry Pi’s 3. It’s not cheap 0. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

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

Mark 1, 7 36 I have a few questions, however. The FQP30N06L is designed to be driven from voltages of at least 5V, which is the minimum voltage that they specify on-resistance.
