MAX5992A Evaluation Kit

2x2P PD Configuration

Jumper JU1 sets the 2x2P PD configuration of the devic-

es. See Table 1 for shunt positions.

Power Good (PG)

Jumper JU2 sets the PG output for 2x2P PD and multi-PD

configurations. See Table 2 for shunt positions.

Multi-PD Redundancy Configuration

The EV kit provides an option to configure for multi-PD

redundancy operation. Set jumpers JU1, JU2 accord-

ingly and remove resistors R116, R117 for redundancy

configuration.

Jumper JU3 sets the multi-PD redundancy configuration

of U1. See Table 3 for shunt positions.

Jumper JU4 sets the multi-PD redundancy configuration

of U2. See Table 4 for shunt positions.

PD Classification Signature

The EV kit is configured for a Class 5 (> 25.5W) PD

classification by resistors R51 and R56. To reconfig-ure

the PD classification, replace the surface-mount 0805

resistors, R51 and R56. Table 5 lists the PD classification

options.
