What's the best motor controller for tiny robot

I want to build a tiny obstacle avoiding robot using a 3v coreless DC motor. I've been using this L293D to control 5V motors and up, but I can't seem to find a motor controller that works with motors below 5V anywhere. I also have 3V two-step motors, but I would much rather use the 3v coreless DC motor if possible:L293D-Motor-Driver is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. It means that I can control two DC motor with a single L293D IC.Do you have ideas of this such a small motor-controllers exist or do I need to looking for a different solution? All I'm trying to do is have some kind of tiny component that will let me control both (or at least one) of the motors in both directions.Normally I could use L293D, but it requires 5V inputs for the trigger pins as well, but my project will be using only 3.7v.Thank you!
