Hi, I'm looking for an easy way to boost the output of the l297/l298 chipset from a max of 3 amps bridged to 8 amps or so. Is there a way ro hang some mosfets off the l298 h-bridge to up the power or is there a higher current h-bridge that is compatable with the l297. Amplexus  |

| the 297/98 combo. you can remove the 298 and use a 74aco8 and 4 FET,s have a look at www.pchilton.co.uk/images/stepperdriver.jpg I have used IRF50N06 plus FR304 diodes he used IRL640 as it is a 200 volt device with out diodes. i have read of people using two 298 in parallel but this is still not enough for what you want to do. Hope this may help, Michael an eccentric English man. P.S. or a 74HC08 |
