Timing capacitor used by
the dynamic overload
protection. Typical
application is 4.7μF for a
1200ms cycle
External modulation
input. Needs DC
decoupling to the AC
source. if not used, can
be left open.
Logic control input: see
truth table
Logic output (open
collector). Normally in
HIGH IMPEDANCE,
goes LOW when current
or thermal overload
occurs
In stand-by mode, the
voltage on MI is routed to
LNBA pin. Can be left
open if bypass function is
not needed
