expected that the comparator output will be ignored.
The session valid comparator is a TTL-level input that determines when V
enough for a session to start. Both the A-device and the B-device use this comparator to
detect when a session is started. The A-device also uses this comparator to indicate when
a session is completed. The session valid threshold of the ISP1301 is between
0.8 V and 2.0 V.
The session end comparator determines when V
threshold of 0.2 V to 0.8 V.
