It’s not easy being a current-sense resistor: so much is expected of this basic function of determining current flow by simple measurement of voltage across a known resistance, then applying Ohm’s Law ...
The fundamentals to translating the analog world into the digital domain reduces to a handful of basic parameters. Voltage, current, and frequency are electrical parameters that describe most of the ...
• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...
