The MAX8555A evaluation kit (EV kit) demonstrates the
functionality of the MAX8555A ORing MOSFET controller,
which provides redundancy and fault isolation to
highly reliable power systems. The EV kit is configured
for 1.5V operation, but can also be modified to operate
in 0.5V to 3.3V power systems.
During startup, the EV kit monitors the voltage difference
between the power supplies VIN1 or VIN2 and a
system power bus VOUT. Once the voltage difference
is less than 50mV (typ), the MAX8555A turns on the two
associated ORing MOSFETs, connecting the power
supply to the system power bus. Once the MOSFETs
are fully on, the EV kit circuit monitors the supply current
and voltages to protect against undervoltage
(UVP), overvoltage (OVP), and reverse-current fault
conditions. PC board pads for fault output signals are
provided for circuit monitoring.
