USB Host Power; This pin is connected to the remote
USB Host Power Switch’s Enable pin. In response to
a fault contition, signalled on the nUSBHOVRCURR
pin, the LH7A404 can assert this pin, which causes
the power switch shut down.
USB Host Overcurrent; The overcurrent input is used
to indicate to the host a fault has occurred, resulting in
current limiting. The LH7A404 can be programmed to
cause the remote power switch to shut off by assert-
ing USBHPWR in response to an nUSBHOVRCURR
assertion.
