The MAX5932 evaluation kit (EV kit) is a fully assembled
and tested hot-swap controller circuit board. The
MAX5932 surface-mount, hot-swap controller provides
foldback current limit, programmable undervoltage
lockout (UVLO), programmable current-limit timer, and
programmable output-voltage slew rate through an
external n-channel MOSFET. The MAX5932 is pin and
function compatible with the LT1641-1. This EV kit can
be used to evaluate either part. The EV kit provides a
power-good output signal that indicates the status of
the output voltage.
The MAX5932 EV kit is configured for a 48V input application
and up to 4.7A of output current. Power for the circuit
can be provided from a 40V to 80V DC source used
in industrial environments or in automotive 42V power
systems. The overcurrent timeout limit is configured to
10ms. The UVLO threshold and the output voltage
threshold are configured to 39V and 45.8V, respectively.
The MAX5932 controls an n-channel MOSFET and provides
current regulation during startup. The current-limiting
and voltage threshold features are configurable by
replacing components on the EV kit board.
The EV kit can also be used to evaluate the
MAX5933A/B/C/D/E/F and MAX5947A/B/C hot-swap
controllers after replacing the MAX5932.
Warning: The MAX5932 EV kit is designed to operate
with high voltages. Dangerous voltages are present on
this EV kit and on equipment connected to it. Users who
power up this EV kit or power the sources connected to it
must be careful to follow safety procedures appropriate to
working with high-voltage electrical equipment.
Under severe fault or failure conditions, this EV kit may
dissipate large amounts of power, which could result in
the mechanical ejection of a component or of component
debris at high velocity. Operate this kit with care to avoid
possible personal injury.
