project board and pcb?
i have a stepper motor with its deriving circuit
on the project power, the circuit does work with a single power supply (+5 1A), however the same circuit on PCB doesn't work with the same power supply, it needs 2 different supplies (+5 1A, and +5 500mA). where +5 1A supply used as motor supply, and +5 500mA used for the deriving circuit
i want to know why, and how to solve this problem
There is a good reason for the two supplies, even though the voltage is the same.
The stepper motor is driven with pulses that have a very high dv/dt (due to MOSFET switching, which is common for these circuits). So every time the motor driver activates, a sharp current spike is produced and the supply voltage undergoes a similar small negative voltage spike, large enough to confuse your driver logic.
In theory, you could power both from the same source, but practically you will find it VERY difficult to provide the clean voltage that your control circuit needs, while the power driver is causing the supply to vacillate.
The best way to do this with one supply is to have a power source with much more capacity (stiffer) than what is just sufficient for the combined loads, and then heavily filtered with high-frequency devices, that are carefully placed in the circuit to maintain a minimum of ESR.
It is usually cheaper to have two smaller supplies.
