APPLICATIONS INFORMATION
Shutdown
The LT4356 can be shut down to a low current mode when
the voltage at the SHDN pin goes below the shutdown
threshold of 0.6V. The quiescent current drops to 7μA for
the LT4356-1 and 60μA for the LT4356-2 which leaves the
auxiliary amplier on.
The SHDN pin can be pulled up to VCC or below GND by
up to 60V without damaging the pin. Leaving the pin open
allows an internal current source to pull it up and turn
on the part while clamping the pin to 2.5V. The leakage
current at the pin should be limited to no more than 1μA
if no pull-up device is used to help turn it on.
Supply Transient Protection
The LT4356 is guaranteed to be safe from damage with
supply voltages up to 100V. Nevertheless, voltage tran-
sients above 100V may cause permanent damage. During
a short-circuit condition, the large change in current owing
through power supply traces and associated wiring can
cause inductive voltage transients which could exceed
100V. To minimize the voltage transients, the power trace
parasitic inductance should be minimized by using wide
traces. A small surge suppressor, D2, in Figure 9, at the
input will clamp the voltage spikes.
