I've read some answers about resistors used in MOSFET and found that 1kOhm to 100kOhm is used to take MOSFET off when MCU is powering and a resistor from 10Ohm to 200-500Ohm is placed between gate and signal to keep out oscillation.
I've a question about how much current there is on this two resistors and how to choose their power rate. And, resistor values can influence MOSFET speed?
My doubts are: Since resistor tell how much current go through it, pulldown resistors of 10kOhm and 100kOhm should consume 0.33mA and 0.033mA respectively. And 100kOhm should be best choice for low power applications where several MOSFET are used. For gate resistor between MCU pin and MOSFET gate I'll have a 100Ohm resistor with maximum current of 33mA. But MOSFET really drain current from my signal pin? and it's correct to calculate currents in this way on resistors(since there is voltage divider, I'll have very very low current on 10-100kOhm resistor? but MOSFET influence this current?). Don't knowing how to answer about this I don't know if I should use a 1/8W resistor or 1/25W resistor.
About switching speed, this resistors influence switching on load? For example, 400-500Khz and 1Mhz are influenzed? or 10Mhz?
I'm doing this considerations on a low voltage and current MOSFETS, like 3.3v gate and 5v Source-drain, up to 1A drain. Something like this as MOSFET www.ti.com/lit/ds/symlink/csd13202q2.pdf .
My main question is quoted in the upside, additive question is to explain what I'm on doubt. I'd like a more pratical example based on values on datasheet I've liked to better reuse this on other MOSFETS.
