Monolithic Power Systems Inc. EV5026-V-00A

Overview

EV5026-V-00A from Monolithic Power Systems is a 4-layer, 7.15 cm × 6.35 cm evaluation board for the MP5026GLRT hot-swap Intelli-Fuse IC, supporting 2.7–16 V input, 20 A continuous output current, and integrated OCP/SCP/OTP/OVP/UVP protection. It enables reference-circuit validation of inrush limiting, load-enabling, fault reporting, and current monitoring in live-insertion power systems.

For engineers reviewing the EV5026-V-00A datasheet, EV5026-V-00A pinout, EV5026-V-00A application, or EV5026-V-00A equivalent, this board provides verified test waveforms (hot-plug, OCP, SCP, OVP recovery), configurable thresholds via external resistors (RISET, ROV_UP, REN_UP), and direct access to critical signals including IMON, FLTB, PG, and TIMER for real-time system integration analysis.

Technical Context

The EV5026-V-00A implements the MP5026's full protection stack-including 25 A steady-state OCP (RISET = 12 kΩ), 50 A short-circuit limit, 13.3 V rising OVP threshold (ROV_UP/ROV_BOT = 100kΩ/10kΩ), and 5.6 V UVP enable threshold-using discrete resistor networks and on-board test points for precise threshold tuning and signal probing.

It supports dual startup modes (VIN-triggered and EN/UV-controlled), delivers 9.9 ms soft-start time with CSS = 100 nF, and integrates a 2.8 mΩ RDS(ON) internal MOSFET with die temperature sensing and current mirroring-eliminating external sense resistors and thermal sensors in validated reference designs.

FAQ

What is the maximum continuous output current supported by the EV5026-V-00A?

The board demonstrates the MP5026's capability to deliver up to 20 A continuous output current at room temperature, as confirmed by thermal imaging and sustained load testing per the Rev. 1.0 test report. This rating assumes proper PCB copper area, ambient airflow, and input voltage ≥ 5 V.

How do I configure over-voltage protection on the EV5026-V-00A?

OVP is set using external resistors ROV_UP (100 kΩ) and ROV_BOT (10 kΩ) connected to the OV pin, yielding a rising threshold of 13.3 V and falling threshold of 12.5 V. Resistor values can be recalculated using the MP5026 datasheet's OVP divider equation; D1 (SMDJ13A) provides secondary clamping.

Can the EV5026-V-00A be used with input voltages above 12 V?

Yes, but the onboard TVS diode D1 (13 V) must be removed and replaced with a higher-voltage-rated TVS (e.g., SMDJ15A for 15 V systems) to avoid unintended clamping. All other protections-including OVP, UVP, and OCP-remain functional with appropriate resistor reconfiguration.

What signals are accessible via test points on the EV5026-V-00A?

All critical control and monitoring pins are routed to 34 labeled test points: VIN, VOUT, EN/UV, LOADEN, TIMER, SS, ISET, IMON, PG, FLTB, OV, and all AGND/PGND nodes. These allow oscilloscope probing, loop injection, and real-time fault diagnostics without soldering or modification.

Does the board support both automatic and manual startup modes?

Yes - it supports two independent startup methods: VIN-triggered (EN/UV switch ON before applying input) and EN/UV-triggered (apply VIN first, then toggle the SW switch). Each mode produces distinct soft-start and fault-handling waveforms documented in Sections 7–8 of the Rev. 1.0 test report.

Is the MP5026GLRT IC soldered to the EV5026-V-00A board?

Yes, the MP5026GLRT is permanently mounted in an LGA-26 (4 mm × 4 mm) package on the board. The IC is not socketed or removable; evaluation is performed via its exposed pins, test points, and functional interfaces as shown in the schematic (Figure 1) and BOM (Page 6).
