Hi

I've made new design with new IC FAN7388, regards to its data sheet , it is capable to drive array of mosfet very smoothly, in low voltage and amper before the chopping switching act ,every...

please find attached PDF

I’ve decide to switch from H bright to half bright with array of MOSFET, hence below is the schematic of what I suppose to be work with following assumption
To initiate the lower array just use...

Thanks for reply, yes I've already run 2 or 4 phase but 5 phase is something else , as you well know and regards to many article it will run as 4000 rpm with high power, as I stated before...

Yes there is better IC rather than H bridge & Fet IC , but this is fun project to pull out somethings works beside somethings make, and as I stated the main issue is to hardware or software...

Hi Daniellyall

Thanks for reply and concern , but always posting a thread is the last step when you have not ready to use solution, those chip are awesome but I wasn't lucky to find it rather...

Hi H500
Thanks for reply , some guy says try hardware chopping implementation, it is so fast and realistic, hence I've decide to use opamp such as LM324 to comparable current sense voltage with...

many thanks H500
I didn't draw any schematic just used single L298 for each phase , connect tied input & tied currents sense to Atmega, I've decide to simulate the L297 performance with Atmega...

Hi every one
I've tried to replicate L297-driven-L298 scheme for my 5 phase oriental motor pentagon stepper motor, but I've find
L297 only use for 4 wire motors, hence I've decide to use an...
