HELP!!!!!!need to control 4.8v dc motors - shaunundergrad - Aug 22 4:55:00 2003

hi guys,

i've made a mistake and bought 2 4.8v dc motors that are too big for
my 'h' bridge ic....these are motors that will probably run at 2a
normal load, stall current 7a. i don't know what i need to control
this amount of power, any help appreciated....needs to be reasonably
simple only home project to help me learn pics in preperation for
next semesta

best regards

shaun

Re: HELP!!!!!!need to control 4.8v dc motors - Emmanuel Gonzalez - Aug 22 8:52:00 2003

i suggest that you buy another h-bridge that will be compatible with your dc
motors...try using A3951 pwm motor driver from Analog Devices...they are
suitable for motors like yours...
