CAT6500
3.0 A Power Selector Switch
Description
CAT6500 is an automatic power switch designed to select between
two power sources and direct that power to a load for battery charging
or system power.
CAT6500’s power inputs withstand voltages of up to 18 V and
protect the downstream load from voltages exceeding 7 V. In the event
of a polarity reversal at either input CAT6500’s internal power
switches will shut off to prevent discharge of the system’s internal
power source.
Low resistance power switches handle currents in excess of 3 A and
when OFF block current flow in both directions. CAT6500 can operate
in reverse mode in which internal system power is be directed to either
of the power input ports for powering an external device, such as a
USB On−The−Go appliance.
