Monolithic Power Systems Inc. EV5016-QH-00A

Overview

EV5016-QH-00A from Monolithic Power Systems is a programmable current-limited protection switch IC with integrated 43mΩ power FET, 2.7V–15V input range, fixed 2.5A current limit (ILIMIT pin floating), 26V absolute max transient rating, and output overvoltage clamp. It performs hot-swap inrush control, reverse polarity blocking, and hiccup-mode OCP in USB3.1 power delivery paths.

For engineers reviewing the EV5016-QH-00A datasheet, EV5016-QH-00A pinout, EV5016-QH-00A application, or EV5016-QH-00A equivalent, key selection criteria include programmable slew rate via DV/DT pin, MODE-pin-selectable OVP threshold, thermal shutdown with auto-retry, and QFN10 (1.5mm × 2mm) package compatibility with high-density PCB layouts.

Technical Context

The EV5016-QH-00A implements a monolithic electronic fuse architecture with internal gate driver and current-sense amplifier. Its soft-start behavior is controlled by external capacitor on DV/DT pin and MODE pin logic state, enabling adjustable output voltage ramp rates from 3.8 V/ms (typical) to slower profiles.

OVP clamping is active at the output node and configurable via MODE pin connection (e.g., grounded for 6.8V clamp, open for 13.2V clamp). Hard-short protection triggers within <1 µs, initiating hiccup-mode current limiting with thermal foldback and auto-retry recovery.

FAQ

What is the function of the MODE pin on EV5016-QH-00A?

The MODE pin selects the output overvoltage clamp threshold: grounded for 6.8V (suitable for 5V logic systems), or left open for 13.2V (compatible with 12V peripherals). This dual-threshold capability eliminates BOM variants for mixed-voltage platforms and avoids external voltage dividers.

Can EV5016-QH-00A be used without connecting the ILIMIT pin?

Yes. With ILIMIT pin floating, the device defaults to a fixed 2.5A current limit (typical), verified in EVB test reports. This configuration simplifies prototyping and reduces component count for applications where 2.5A protection suffices.

Does EV5016-QH-00A provide reverse current blocking?

Yes. The device blocks reverse current flow when VOUT exceeds VIN, as confirmed by functional description and electrical specification tables in the MP5016 datasheet. This protects upstream sources such as battery packs or shared power rails from backfeed damage.

What is the recommended PCB layout practice for thermal management?

Mount the QFN10 package with its exposed thermal pad soldered to a minimum 100 mm² copper pour connected to GND via ≥4 thermal vias (0.3mm diameter). This achieves ≤45°C/W junction-to-board thermal resistance, ensuring reliable operation at 2.5A continuous load per EVB thermal imaging results.

How does the DV/DT pin control soft-start behavior?

The DV/DT pin accepts an external capacitor that sets the output voltage ramp rate. A 1nF capacitor yields ~3.8 V/ms (typ), while larger values reduce slew rate linearly. This direct C-based control eliminates timing resistors and ensures predictable, repeatable inrush current profiles across temperature and voltage.

Is EV5016-QH-00A RoHS and halogen-free compliant?

Yes. Per MPS documentation, all MP5016 devices-including EV5016-QH-00A-are lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU. Full compliance status and material declarations are published in MPS Quality Assurance portal.
