Dear friends


I'm planning to use a darlington pair IC to power my bot.

I dont want to use discrete transistors to make it....

can √*nyone suggest the IC numbers for them...

Also would using a darlington pair have any significant disadvantages over a H-bridge?

hi,
maybe you could use TIP122.....ita data sheet is available in the following link www.fairchildsemi.com/ds/TI/TIP120.pdf
all the best...............

hi
i think uln2803 also is nothing but darlington drivers......
check out the datasheets for details...

the biggest advantage of using a darlington configuration is the current boost it provides u....
specially needed for driving motors..

HI,
ULN2003 - 7 darlington o/p
ULN2803 - 8 darlington o/p

2v to 35v, 500ma!!

ea abt rs.10/- anywhere.

hi....

Well, all the driver ICs that come for a high power motors are actually Darlington pairs only, becasue a single transisor cannot give such a high current gain. So go for the IC with higher current ratings.
Best of Luck
