Yes,
I am currently working on a project of which a motor has to be controlled (0 to 50) Hz by a PIC18F.
I'm planning on using IRF840 N-channel mosfet, controlled by an IR21094 gate driver.
I'm currently testing these components with the model given with the datasheet of the gate drivers.
Problem.
I am currently having problem with getting the mosfets to work, after hours of searching on the internet and this forum i concluded that it must be the Bootstrap circuit, i'v tried different capacity (around 4.7 uF) but nothing works.
Can anyone give a help or guide me in the right way? many thanks in advance
