The MAX8535 evaluation (EV) kit circuit demonstrates
the functionality of the MAX8535 ORing MOSFET controller
that provides redundancy and fault isolation to
highly reliable power systems. The MAX8535 EV kit
board operates in 12V systems.
During startup, the EV kit monitors the voltage difference
between a power supply and a power bus. Once
the voltage difference is less than 0.4V, the MAX8535
turns on two ORing MOSFETs, linking the power supply
and power bus. Once the MOSFETs are on, the EV kit
monitors the load current and voltages to protect
against undervoltage (UVP), overvoltage (OVP), and
reverse-current fault conditions.
The OVP and UVP thresholds are adjustable and can
be disabled. The UVP threshold is set to 8V and the
OVP threshold is set to 13.75V. A FAULT-bar signal output
is provided for circuit monitoring.
