com AAT4621 PC Card Current Limit Interface and Capacitor Charger General Description The AAT4621 SmartSwitch is a current limited Pchannel MOSFET power switch designed for highside load-switching applications in PC Card GSM/GPRS/3G modem cards.
Used in conjunction with a super capacitor, the AAT4621 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 AAT4621 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 tem...
