wire fault ( WFLT ) (see Notes 10 and 11)
PARAMETER

kΩ
RL(N) Phantom-drive load resistance detected as normal
2.9 5.5 kΩ
NOTES: 10. The wire-fault circuit recognizes a fault condition for any phantom-drive load resistance to ground greater than RL(O) or any load
resistance less than RL(S). Any resistance in the range specified for RL(N) is not recognized as a wire fault. A fault condition on either
PHOUTA or PHOUTB results in WFLT being asserted (low).
11. Resistor [RL(S), RL(O), RL(N)] connected from output under test to ground, other output loaded with 4.1 Ω to ground.
