Bipolar stepper motor control

I am trying to power a bipolar stepper motor using an SN754410NE Hbridge. The motor has the following specs:

Rated current: 1.7 A
Rated Voltage: 2.4 V
Phase Resistance: 1.5 Ohms
Phase Inductance: 2.5 mH

What voltage and current power supply do I need to use, and do I need to regulate current through the hbridge? Thanks

Using a 754410 that has a maximum output current of 1A for 1.7A rated motor does not seem right. The 754410 does not limit current nor allow microstepping either. A much better choice would be a DRV8825 stepper driver. Pololu has those drivers and a good page on how to set them up and use them.

I agree with @groundFungus - that motor is not intended to be controlled with a h-bridge driver. It needs a specialized stepper motor driver that can use a high voltage power supply and limit the current to protect the motor.

DRV8825 stepper driver is what you need, that motor needs current control, not voltage control.
