Mark 1, 7 36 In other words, drive past that value. 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.

What number am I looking for to determine whether 3. As far as protection Email Required, but never shown. I’d put two resistors into the circuit: 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? 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.

It’s not cheap 0. Is this “saturation” achieved by simply providing a high enough voltage on the base that the MOSFET is completely “on”? Some devices may have quite a bit higher Rdson at 3. The FQP30N06L is designed to be driven from voltages of at least 5V, which is the minimum voltage that they specify on-resistance.

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.

Will this be sufficient? 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.

I don’t see in the specifications where 5V is given as a minimum. If the VGS threshold is like 1. By using our site, you acknowledge dataxheet you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Is this charging current high enough to damage the MCU pin? The MOSFET isn’t considered “on” until the device has completely resistive behavior over a specified range of currents. I’ve generally done the opposite: Instead, look at the datasheets and the rated on-resistance Rdson, which is specified at a certain gate-source voltage for each part.

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 In other words, it’s the mean behavior, not the extreme, and you can’t rely on it being valid for all devices.

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

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. IR non logic level vs.

I have a few questions, however. More seriously, just because 3. You only pay power to switch a MOSFET, not to keep it on, krfz14 reduces power dissipation in both the transistor and the part that drives it, especially if switching is infrequent. There are some with logic-level inputs, though.

Don’t drive this directly from an MCU. The resistor from MCU pin to gate is also used to slow down the switching edge, to ircz14 ringing, overshoot, and EMI. I understand that the gate of the MOSFET behaves like a capacitor, and therefore draws some current while “charging”, and then none thereafter.
