ODT (Overcurrent Disable Time)
If the LNB output current exceeds 900 mA typical, for more than
48 ms, then the LNB output will be disabled and the OCP bit will
be set.
Short Circuit Handling
If the LNB output is shorted to ground, the LNB output current
will be clamped to 900 mA, typical. If the short circuit condition
lasts for more than 48 ms, the A8286 will be disabled and the
OCP bit will be set.
Auto-Restart
After a short circuit condition occurs, the host controller should
periodically re-enable the A8286 to check if the short circuit has
been removed. Consecutive startup attempts should allow at least
5 s of delay between restarts.
In-rush Current
At start-up or during an LNB reconfiguration event, a tran-
sient surge current above the normal DC operating level can be
provided by the A8286. This current increase can be as high as
900 mA, typical, for as long as required, up to a maximum of
48 ms.
DC current
The A8286 can handle up to 700 mA per channel individually,
or 950 mA to both channels simultaneously, during continuous
operation.
Tone Detection
A 22 kHz tone detector is provided in each channel of the A8286
solution. The detector extracts the tone signal and provides it as
an open-drain signal on the TDO pins. The maximum tone out
error is ±1 tone cycle, and the maximum tone out delay with
respect to the input is 1 tone cycle. Detection thresholds are given
in table 1.
