Gate driver module for mosfet/IGBT
« on: November 30, 2023, 06:43:59 pm »
Hello,

Im looking for gate driver module to switch n-mosfet/IGBT.
It should have capability to adjust duty cycle and frequency.
Frequency should go higher than what ne555 can do, minimum 1MHz. Signal should be square wave.

This seems decent:

What kinda options you guys know? I would rather buy ready module rather that try to build one.

I suppose you would be alright with than module.
I'm a little leery of the 6A current capability. Suspicion is based on other products making unrealistic claims.
Switching speeds of IGBts are quite a bit slower than MOSFETs . Typical IGBTs range from 20Khz to 80Khz. Where as MOSFETs will range much higher
The 555 timers can very. The TLC555 has a maximum frequency of around 2Mhz and the XTR655-D goes as high as 4Mhz. Aside from maximum supply voltages they are both drop in replacements for the NE555
