Application Recommendations
Best practices V
IN
decoupling is required, a 1
μ
F capacitor is
recommended.
Coupling from the ENABLE_X pins to the sensitive UV and
OV pins can cause false OV/UV events to be detected. This
is most relevant for ISL8700A, ISL8702A, ISL8704A parts
due to the ENABLEA and OV pins being adjacent. This
coupling can be reduced by adding a ground trace between
UV and the ENABLE/FAULT signals, as shown in Figure 15.
The PCB traces on OV and UV should be kept as small as
practical and the ENABLE_X and FAULT traces should
ideally not be routed under/over the OV/UV traces on
different PCB layers unless there is a ground or power plane
in between. Other methods that can be used to eliminate this
issue are by reducing the value of the resistors in the
network connected to UV and OV (R2, R3, R5 in Figure 16)
or by adding small decoupling capacitors to OV and UV (C2
and C7 in Figure 16). Both these methods act to reduce the
AC impedance at the nodes, although the latter method acts
to filter the signals which will also cause an increase in the
time that a UV/OV fault takes to be detected
.
When the ISL870XA is implemented on a hot swappable
card that is plugged into an always powered passive back
plane an RC filter is required on the V
IN
pin to prevent a high
dv/dt transient. With the already existing 1
μ
F decoupling
capacitor the addition of a small series R (>50
Ω
) to provide a
time constant >50
μ
s is all that is necessary.
