The AAT4621IWO-1-T1 from Skyworks Solutions is a current-limited P-channel MOSFET power switch designed for high-side load-switching applications, particularly in PC Card GSM/GPRS/3G modem cards. It functions as a capacitor charger, ensuring that PCMCIA host power ratings are not exceeded during supercapacitor charging.
This device offers dual independent, programmable current limits, adjustable via external resistors with ±10% accuracy. The operating voltage range is from 3.0V to 5.5V. Key electrical specifications include a typical quiescent current of 40μA, decreasing to less than 1μA in shutdown mode, and a typical RDS(ON) of 65mΩ at 3V.
The AAT4621IWO-1-T1 incorporates features like reverse current blocking, a power loop, and a System READY output to indicate when a supercapacitor is fully charged. It operates within a temperature range of -40°C to 85°C and is available in a 14-pin TDFN33 package.
Applications include capacitor charging, CF Card port power protection, Express Card GSM/GPRS/3G modems, and PC Card GSM/GPRS Class 10/12 modems.
