accomplished thanks to the fast response of the
ENT input and the prompt oscillator start-up. This
helps designers who want to implement the
DiSEqC
protocols(*).
In order to improve design flexibility and to allow
implementation
of
newcoming
control standards, an analogic modulation input
pin is available (EXTM). An appropriate DC
blocking capacitor must be used to couple the
modulating signal source to the EXTMpin. When
external modulation is not used, the relevant pin
can be leftopen.
Two pins are dedicated to the overcurrent
protection/monitoring: CEXT
overcurrent protection circuit works dynamically:
as soon as an overload is detectedin either LNB
output, the output is shut-down for a time Toff
determined by the capacitor connected between
CEXT and GND. Simultaneously the OLF pin,
that is an open collector diagnostic output flag,
LNB
remote
and
OLF.
The
from HIGH IMPEDANCE state goes LOW. After
the time has elapsed, the output is resumed for a
time t
on
=1/15t
off
(typ.) and OLF goes in HIGH
IMPEDANCE. If the overload is still present, the
protection circuit will cycle again through t
off
and
t
on
until the overload is removed. Typical t
on
+t
off
value is 1200ms when a 4.7
μ
F externalcapacitor
is used.
This dynamic operation can greatly reduce the
power dissipation in short circuit condition, still
ensuring excellent power-on start up even with
highly capacitive loads on LNBoutputs.
The device is packaged in Multiwatt15 for
thru-holes mounting and in PowerSO-20 for
surface mounting. When a limited functionality in
a smaller package matches design needs, a
range of cost-effective PowerSO-10 solutions is
also offered. All versions have built-in thermal
protectionagainst overheatingdamage.
