applied.
To test the voltage limiter, apply a transient to the 12V
Input. One method of coupling a transient without
backfeeding the 12V supply is shown in the Connection
Diagram, attached. If the input transient is short the
output simply limits at 16V and then recovers to 12V.
If the transient is sustained, the output will rise to 16V,
regulate there and then shut down. The exact timing
and the dividing line between "short" and "sustained" is
a function of the input waveform amplitude and shape
(see the data sheet). The timing interval is controlled
by CTM R and the TM R pin according to equations in
the data sheet. After faulting off, the LT4356-3 latches
off. Reset by cycling power or by toggling the SHD N#
pin.
