The AAT4621IWO-T1 from Skyworks Solutions is a current-limited P-channel MOSFET power switch designed for high-side load-switching in PC Card applications like GSM/GPRS/3G modems. It functions in conjunction with a super capacitor to prevent exceeding PCMCIA host power ratings.
This device offers two independent, programmable current limits, with the AAT4621 variant ranging from 75mA to 1200mA. The current limit accuracy is within ±10% over the normal operating temperature range of -40°C to 85°C. It operates within a voltage range of 3.0V to 5.5V and features a low quiescent current of typically 40µA, decreasing to less than 1µA in shutdown mode.
Key features include reverse current blocking protection, a power loop, and a System READY output to indicate when a super capacitor is fully charged. The AAT4621IWO-T1 is available in a 14-pin TDFN33 package, suitable for surface mounting.
Applications include capacitor chargers, CF Card port power protection, Express Card and PC Card modems, and WiMAX cards. Its design ensures super capacitor charging without exceeding PCMCIA specifications.
