AAT4620, PCMCIA Current Limit Interface and Capacitor Charger

AAT4620 PCMCIA Current Limit Interface and Capacitor Charger General .
The AAT4620 SmartSwitch is a current limited Pchannel MOSFET power switch designed for highside load-switching applications in PCMCIA GSM/GPRS/3G mode.

Features

* SmartSwitch™
* VIN Range: 3.0V to 5.5V Dual Independent Current Limits
* 100mA to 1200mA
* ±10% Current Accuracy
* 20°C Temperature Band Reverse Current Blocking Pr

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
