Overview
5V/3V PC Card Power Switch General Description The AAT4651 SmartSwitch is a single channel PC card (PCMCIA) power switch.
It is used to select between two different voltage inputs, each between 2.
7V and 5.
5V.
An internal switch powers the circuitry from whichever input voltage is higher.
The device's output, VCC, is slew rate controlled and current limited, in compliance with PC card specifications.
The current limit response time to a short circuit is typically 1µs.
The internal P-channel MOSFET switches are configured to break before make; that is, both switches cannot be closed at the same time.
Controlled by a 2-bit parallel interface, the three states for VCC are VCC5, VCC3, or ground.
