12V/5V Hot-Plug Switch

3

ELECTRICAL CHARACTERISTICS (continued)

Note 1: All voltages are referenced to ground. Currents entering the device are specified positive, and currents exiting the device

are negative.

Note 2: This supply range guarantees that the LOAD_ voltage is not clamped by the overvoltage limit.

Note 3: Supply current specified with no load on the LOAD_ pin.

Note 4: Guaranteed by design; not production tested.
