DESCRIPTION
Demonstration circuit 1819A features the LTC
dual ideal diodes. Each independent ideal diode can be
used to replace a standard diode for improved low forward
drop in applications requiring maximum headroom and
overall system efficiency.
The input supply voltage ranges are from 1.7V to 5.5V for
each input/output pair. As initially configured, LTC4415 can
provide a maximum current limit of 4A for each diode,
but is jumper-selectable up to 6A (internal current limit).
The voltage of the current limit pins, CLIM1 and CLIM2,
can also be monitored for a scaled representation of the
output current.
For evaluation, each diode can be controlled by the EN-
ABLE CONTROL jumper, JP1, or by the enable input pins,

the user can apply input voltages and loads on each diode
independently. Selecting PRIORITY allows the LTC4415 to
automatically switch over between inputs when the proper
input voltage threshold on IN1 is achieved.
Status and warning LEDs and test points are provided for
the logic output pins STAT1, STAT2 and WARN1, WARN2,
respectively.
Optionally, the LTC4415EDHC version can also be used
for evaluation. It is a pin-compatible drop-in replacement.
