1. 1 The Max Peak value represents short current spikes drawn for durations of lt 50us On the 12V supply the peaks correspond to the pulse width modulated switching of the motors These values are calculated from the average of Peak ripple current 2 sigma measured at 5 DC voltage The Max Rms value is the average of the maximum RMS current drawn during this operating mode These values are calculated from the average of RMS current 3 sigma measured at nominal DC voltage The typical current is calculated from the average of all RMS current drawn during this operating mode measured at nominal DC voltage The Max DC power is calculated from the typical DC power 3 sigma measured at nominal DC voltage This value takes into account that the peak currents on the 5V and 12V do not occur at the same time The Typical DC power is calculated from the average RMS DC power drawn during this operating mode measured at nominal DC voltage This value also takes into account that the peak currents on the 5V and 12V do not occur at the same time The Max AC power is calculated from the typical AC power in tabletop drives 3 sigma The Typical AC power is calculated from the average of AC power drawn in tabletop drives The motor start modes draw the most current from the 12V supply so they are shown separately These events last lt 1 second and occur at a duty cycle of less than 25 The Max values for each mo
