• 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 ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

The ISL6742B is an advanced double-ended PWM controller featuring synchronous rectifier control output with adjustable delay/advance and average current signal. The device is ideally suited for both ...

Brushless dc motors have the advantages of high reliability and smaller size, but the absence of brushes can pose challenges. One challenge is the requirement for electronic commutation and control, ...

Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...
