L8560 Low-Power SLIC with Ringing

Power Ringing
(continued)
At the trip point, the internal current repeater will force I
RTSP
to be equal to I
RTSN
and V
RTSP
will be equal to V
RTSN
,
which is –8.2 V. Thus, at the trip point:
Thus:
Solving for V
DCOUT
, the voltage at DCOUT at the ring trip point is given by:
The loop current at ring trip is given by:
I
LOOP(TRIP)
= (V
DCOUT
)/(
β
DCOUT
)
For the L8560, the gain (
β
) at pin DCOUT is 41.67 V/A.
Capacitors C
2
and C
4
, along with resistors R
2
and R
4
, respectively, form low-pass filters to filter the ac voltage seen
at DCOUT before it is applied to the ring trip comparator input. The lower the pole of the filter, the less the ripple,
but also the slower the state transition at NSTAT. Poles in the neighborhood of 2.5 Hz—3 Hz are suggested, as
given by:
