AAT4620 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...
