Abstract: Current-limit switches are virtually ubiquitous in system controls. They provide a safe means for regulating the current delivered to a load circuit. The switches allow the load current to increase to a programmed limit but no higher. This application note illustrates the implementation of a digitally programmable current-limit switch using MAX890L a current-limited, high-side P-channel switch and MAX5160 digital potentiometer Maxim > App Notes > A/D and D/A CONVERSION/SAMPLING CIRCUITS POWER-SUPPLY CIRCUITS Keywords: current limited, current-limit, switch, digital potentiometer, digital pots, P channel switch, switches Aug 17, 2000 APPLICATION NOTE 298 Current-Limit Switch Is Digitally Programmable Abstract: Current-limit switches are virtually ubiquitous in system controls.
