PRODUCT DATASHEET AAT4672 SmartSwitchTM General Description The AAT4672 SmartSwitch™ is a member of AnalogicTech’s Application Specific Power Management IC™ family. This device is a dual input, single output power supply selector switch, designed to operate from USB ports, AC adapter inputs, batteries, or any other power supply with an input voltage up to 6V. The AAT4672 connects the supply on the MAIN pin to the OUT pin through a very low on-resistance power MOSFET www.DataSheet4U.com when the device is enabled, the MAIN pin voltage is higher than the under voltage lockout (UVLO) threshold, and MAIN pin voltage is greater than the AUX pin voltage plus 200mV. The AUX pin connects to the OUT pin only when the MAIN pin voltage drops 0.
