The EV5024-V-00A is an evaluation board designed to demonstrate the capabilities of the MP5024, a fully integrated, PMBus-compliant, compact, hot-swap protection device. The device allows a reference circuit evaluation of the MP5024. It is designed to protect circuitry on its output from transients on its input. It also protects its input from undesired shorts and transients coming from its output. The device can achieve up to 20A of continuous output current (I_OUT) per device at room temperature.

The MP5024 limits the power supply’s voltage drop by limiting the inrush current to the load while a circuit card is inserted into a live backplane power source. It limits the internal MOSFET current (I_FET) by controlling the gate voltage (V_GATE) via a low-power resistor from ISET to ground and soft-start ramp.

The MP5024 provides rich fault protections, such as input voltage (V_IN) over-voltage protection (OVP), I_OUT over-current protection (OCP), short-circuit protection (SCP), and over-temperature protection (OTP). The device detects power MOSFET gate, source, and drain short conditions. The fault status can be indicated with the fault report output (FLT#/ALT#). The MP5024 also provides power good (PG) indication.

The PMBus interface provides V_IN, input current (I_IN), input energy (E_IN), output voltage (V_OUT), I_OUT, input power (P_IN), and output power (P_OUT) telemetry. The MP5024 monitors and reports fault statuses through the PMBus interface.

The MP5024 is available in a QFN-32 (3.5mmx4.5mm) package. The EV5024-V-00A has 4 layers, which are each 2oz, and the total size is 7.15cmx6.35cm.
