An EPC enhancement mode GaN FET will be well driven at
that kind of Vgs - not fully, but sub-100mOhms. Maybe a
better option for you. Provided that you need <= 200V
BVdss.
But it's not clear to me what you're really after - a single
MOSFET, an IC, an IC to drive MOSFETs?
I want to switch ON a load that can have burst currents on 2.5A using a microcontroler. the MOSFET i used is not functioning properly. the voltage drop is too high when I switch it ON. Is there a special circuitry to be used without directly connecting the GATE of the MOSFEt to the ucontroler?
and what is the MOSFET I should use here.
the load is basically a SIM908 which will request for burst currents of 2-2.5A and most of the time the load is off
Hey can you pls advice me of a support circuitry? the one I had I connected the GATE to the MCU and the MCU heats a lot. GATE and SOURSE directly to the Power accrosos the load to GND.
However when I do this, I get about 1.5V less than the supply voltage(3.8V Lipo) at the load. Anyone has a sollution?
should I use a mechanical relay?
May be an IGBT?
is 3.8V at the gate not enough to bias is properly?
