Driving a 3v dc motor

(OP)
Hi,

I'd like to drive a small 3V motor with a mosfet driver ic, but couldn't find a proper one. I'm looking for something like MAX4420, but with lower supply voltage.

RE: Driving a 3v dc motor

One possible solution would be to use a discrete MOS-transistor to drive the motor and a separate control electronics to drive the MOS-transistor.

You should (probably) also have a DC-DC converter to increase the voltage of the control electronics. A higher gate voltage allows the MOS to be properly 'on'.

Note also that the 1.5 ohm output impedance of  MAX4420 seems to be a bit high to drive a motor.
