Monolithic Power Systems Inc. EVKT-MP2695

Overview

EVKT-MP2695 from Monolithic Power Systems is an evaluation kit for the MP2695 single-cell Li-ion/Li-polymer switch-mode battery charger IC. It includes the EV2695-Q-01A evaluation board, EVKT-USBI2C-02 USB-to-I²C interface, cables, and GUI software. The board operates from 4.5V–11.0V input, supports I²C programmability, and ships with default 4.200V charge voltage for Li-ion cells - enabling rapid validation of charging performance, JEITA thermal profiling, and input current regulation in portable power designs.

For engineers reviewing the EVKT-MP2695 datasheet, EVKT-MP2695 setup procedure, EVKT-MP2695 GUI software compatibility, or EVKT-MP2695 hardware configuration, this page delivers verified specifications, PC system requirements (Windows XP/7+, .NET 4.0, 22.2MB free space), physical dimensions (6.3cm × 6.3cm), and functional boundaries including non-volatile OTP programming vs. volatile I²C register writes.

Technical Context

The EVKT-MP2695 provides full hardware and software access to the MP2695's digital control architecture. It enables real-time adjustment of charge voltage (±0.5% accuracy), charge current (±5%), input current limit (±10%), JEITA thresholds, and switching frequency via I²C - all while monitoring battery current through the analog IB pin output.

Hardware-level interaction is mediated by the EVKT-USBI2C-02 interface, which bridges USB 2.0 host communication to the MP2695's I²C bus at standard mode (100kHz) or fast mode (400kHz). All register changes made during live evaluation are volatile and reset on power cycle; permanent configuration requires OTP programming using the GUI's dedicated OTP View and export workflow.

FAQ

Does the EVKT-MP2695 retain I²C configuration after power-down?

No. All I²C register modifications are volatile and reset to factory defaults upon power cycle. To preserve settings across power cycles, users must generate an OTP configuration file via the GUI's OTP View, submit it to MPS FAE for custom part number assignment (e.g., MP2695-XXXX), and program the resulting OTP device onto the EV2695-Q-01A board.

What is the role of the EVKT-USBI2C-02 in this kit?

The EVKT-USBI2C-02 is a dedicated USB-to-I²C bridge that converts USB 2.0 commands from the Windows GUI into I²C transactions targeting the MP2695 on the EV2695-Q-01A board. It handles protocol translation, timing compliance, and electrical level shifting - eliminating the need for external logic analyzers or microcontroller-based interfaces during evaluation.

Can the EVKT-MP2695 evaluate both charging and supplement modes?

Yes. The kit supports full operational mode validation: when VIN > UVLO threshold, the MP2695 operates in buck charging mode; when VIN drops below UVLO falling threshold or thermal shutdown activates, it automatically enters supplement mode - sourcing power from the battery to maintain system rail integrity, observable via GUI status registers and IB pin analog output.

What battery voltage range is supported during evaluation?

The EV2695-Q-01A accepts battery voltages from 0V to 4.45V, covering full Li-ion/Li-polymer discharge and charge profiles. Default termination is set to 4.200V ±0.5%, but users can reconfigure charge voltage between 3.6V–4.45V via I²C or OTP to match cell chemistry or safety margin requirements.

Is thermal protection testing possible with this kit?

Yes. The MP2695 implements die-temperature-based thermal regulation and shutdown. Users can monitor real-time junction temperature estimation via GUI-reported thermal status bits, trigger thermal limiting by increasing load or ambient temperature, and observe recovery behavior as temperature falls below the hysteresis threshold - all without external sensors.

What happens if the USB driver for EVKT-USBI2C-02 fails to install on Windows 10?

Windows 10 may auto-install an incompatible legacy USBXpress driver. Users must manually install the correct version (4.0.0.0) from the kit's \EVKT-USBI2C-02 USB Driver\ folder - selecting x86.exe for 32-bit or x64.exe for 64-bit systems - then verify "USBXpress Device" shows driver version 4.0.0.0 in Device Manager before launching the GUI.
