10 Power Supply Recommendations

All driver channels should be operated after the required power is supplied and stable.

The appropriate capacity of the decoupling capacitor requires a value over 10 μF to reduce the influence of PWM switching noise. The P5V_1, P5V_2, and P5V_SPM pins must connect to 10-μF decoupling capacitors.

Current flow to the driver circuits takes both pattern-layout, line-impedance, and noise influence from the supply line into consideration.
