Power switch for high-side load-switching applications enables safe and speedy charging of supercapacitors in PC modem cards.
AnalogicTech has introduced a P-channel current-limited MOSFET power switch for high-side load-switching applications in PC modem cards Integrating all the circuitry required to limit current, protect the PC card connector, continuously charge the capacitor, and notify the system when it is ready for use, the AAT4620 ensures that a supercapacitor - typically used to average out high pulse currents - can be quickly charged without exceeding the host power supply specifications
