I am trying to choose an H-bridge to allow the use of logic for basic directional control of a three volt brushed DC motor (not PWM signals), however they all seem to have minimum voltages above what I need.
Am I thinking of this wrong? I was thinking of the L293 series drivers, however they have minimum voltages around 4.5v which is too high and also low current limits (0.6-1A). This is the motor I have http://uk.rs-online.com/web/p/dc-geared-motors/4130600/
Would I have to build one using MOSFETS to allow operation at this voltage, because obviously it is easier to use a pre-built IC? Or would the L293 series be lenient and allow me to supply them with 3v so that they run at this level.
Thanks for any responses and I'm sorry if I've missed anything.
