I want to rotate stepper motor using 293 driver ic. But facing a problem that when i connect power supply +Vs as +9Volt and +Vss as +5Volt the my driver ic is heating rise.

My question is this driver ic needed +12 Volt as +Vs?

Can is use +Vs as a +9Volt? and how can i rotate my bipolar stepper motor?

The l293 will not run a motor by itself( well maybe a very weak/small one) it needs a l298 or similar h-bridge to run a bipolar motor
