Application Information
(Continued)
down pin of the LM4916 is also being driven by an open
drain output of an external microcontroller on a separate
supply. This circuit ensures that shutdown is disabled when
powering up the LM4916 by either allowing shutdown to be
high before the LM4916 powers on (the microcontroller pow-
ers up first) or allows shutdown to ramp up with V
(the
LM4916 powers up first). This will ensure the LM4916 pow-
ers up properly and enters the correct mode of operation.
Please note that the SE/BTL pin (Pin 8) should be tied to
GND for Single Ended mode, and to V
DD
for BTL mode.
