Overview
DATA SHEET AAT4620 PCMCIA Current Limit Interface and Capacitor Charger General Description The AAT4620 SmartSwitch is a current limited P-channel MOSFET power switch designed for high-side loadswitching 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 be charged without exceeding PCMCIA specifications.
The current limit is set by two external resistors allowing a ±10% current limit accuracy over the normal operating temperature r...
