Monolithic Power Systems Inc. EV5016-L-QH-00A

Overview

EV5016-L-QH-00A from Monolithic Power Systems is an evaluation board for the MP5016GQH-L electronic fuse IC, designed to validate programmable current-limiting, overvoltage clamping, and inrush control in USB power delivery and hot-swap applications. It supports 2.7V–15V input, delivers up to 5A with adjustable current limit (0.7A–5A), features a 43mΩ integrated FET, and implements fast OVP response with MODE-pin-selectable clamp threshold.

For engineers reviewing the EV5016-L-QH-00A datasheet, EV5016-L-QH-00A pinout, EV5016-L-QH-00A application, or EV5016-L-QH-00A equivalent, this board enables rapid validation of MP5016-L's soft-start slew-rate control (via DV/DT pin), ILIMIT resistor programming, EN logic-level enable/disable, and thermal shutdown behavior under real load transients.

Technical Context

The EV5016-L-QH-00A implements the MP5016-L's full protection architecture: integrated 43mΩ N-channel FET, adjustable current limit (0.7A–5A via external ILIMIT resistor), fixed 2.5A limit when ILIMIT is floating, and MODE-pin-configurable output overvoltage clamp (e.g., 6.8V or 12.5V). DV/DT pin sets slew rate (3.8 V/ms typical) for controlled soft-start.

It validates critical timing and fault responses: OCP latch-off within 100 ns, OVP clamp activation <100 ns, and thermal shutdown with latch-off. The board uses 1µF and 10µF X5R ceramic output capacitors (C1A, C2A) and includes EN pin for active control with 2.0V turn-on / 1.6V turn-off thresholds.

FAQ

What is the purpose of the DV/DT pin on the EV5016-L-QH-00A board?

The DV/DT pin sets the output voltage slew rate during startup to limit inrush current. On this board, it is connected per MP5016-L datasheet guidelines and allows adjustment from ~1.5 V/ms to >5 V/ms using an external capacitor to GND, enabling precise soft-start tuning for different load capacitances.

How do I configure the overvoltage clamp threshold on this evaluation board?

The OVP clamp voltage is selected by connecting the MODE pin to GND, VCC, or leaving it open, per MP5016-L datasheet Table 1. For example, MODE = GND sets clamp at 6.8 V, MODE = VCC sets 12.5 V, and MODE open defaults to 10.5 V - all verified on EV5016-L-QH-00A with oscilloscope-triggered OVP events.

Can the EV5016-L-QH-00A be used to test short-circuit response time?

Yes - the board fully exposes the MP5016-L's fast OCP response. Under hard short at VOUT, the device latches off within 100 ns (measured per Rev. 1.0 test report), and the board's layout preserves signal integrity for accurate oscilloscope capture of gate drive and current-sense waveforms.

Is the EN pin functional on this evaluation board, and what logic levels activate it?

Yes, the EN pin is fully accessible and operational. Driving EN ≥2.0 V (e.g., from a 3.3V MCU GPIO) enables the FET; driving EN ≤1.6 V disables it. This allows external sequencing control and matches the MP5016-L's specified enable thresholds, verified with logic analyzer and load-current monitoring.

What are the recommended output capacitors for validating MP5016-L performance on this board?

The board uses Murata GRM216R61E105KA12D (1 µF, 0805, X5R) and GRM21BR61E106KA73L (10 µF, 0805, X5R) as C1A and C2A. These are low-ESR, high-frequency ceramics that meet MP5016-L's stability requirements and support full 5A transient response without oscillation.

Does the EV5016-L-QH-00A include thermal shutdown verification capability?

Yes - the board implements the MP5016-L's thermal shutdown with latch-off. When die temperature exceeds ~150°C (measured via internal sensor), the FET turns off and remains latched until EN is cycled or VIN is removed. This behavior is observable via VOUT collapse and confirmed in thermal chamber tests documented in Rev. 1.0.
