The MAX5943A evaluation kit (EV kit) circuit demonstrates
the hot-swap, current-limiting, and power-ORing
functions of the MAX5943A. The MAX5943A EV kit is
intended for 7.5V to 37V IEEE® 1394/FireWire® applications.
The MAX5943A controls two n-channel MOSFETs
to regulate load current from an input power supply and
perform low-voltage-drop power-supply ORing. The
MAX5943A EV kit can also be used to evaluate the
MAX5943B/C/D/E versions (refer to the MAX5943 IC
data sheet).
The MAX5943A EV kit features several jumpers to evaluate
different configurations of the MAX5943A. The output
current limit, current-limit timeout period, ORing
threshold, and fault-management features are programmable.
The undervoltage lockout threshold is configurable
by installing external components. Shutdown
mode can be controlled with an on-board switch or with
an external logic signal. A active-low FAULT output signal is provided
for fault condition monitoring.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.
