AAT4620, PCMCIA Current Limit Interface and Capacitor Charger

DATA SHEET AAT4620 PCMCIA Current Limit Interface and Capacitor Charger General .
The AAT4620 SmartSwitch is a current limited P-channel MOSFET power switch designed for high-side loadswitching applications in PCMCIA GSM/GPRS/3G mod.

Features

* VIN Range: 3.0V to 5.5V
* Dual Independent Current Limits ▪ 100mA to 1200mA ▪ ±10% Current Accuracy ▪ 20°C Temperature Band
* Reverse Current Blocking Protection
* Power Loop
* Low Quiescent Current ▪ 40μA Typical ▪ 1.0μA Max with Switch Off
* 65m T

Applications

* in PCMCIA GSM/GPRS/3G modem cards. Used in conjunction with a super capacitor, the AAT4620 will ensure that the power ratings of the PCMCIA host are not exceeded at any time. Featuring two independent, programmable current limits and a power loop, the AAT4620 can ensure that the super capacitor can
