Monolithic Power Systems Inc. EVKT-MP2663

Overview

EVKT-MP2663 from Monolithic Power Systems is an evaluation kit for the MP2663 single-cell Li-ion/Li-polymer battery charger IC, enabling rapid validation of power-path management, I²C-programmable charging parameters (e.g., 4.095V charge voltage, 8–535mA charge current), and thermal protection in portable electronics design.

For engineers reviewing the EVKT-MP2663 datasheet, EVKT-MP2663 pinout, EVKT-MP2663 application, or EVKT-MP2663 equivalent, this kit provides hands-on access to real-time register read/write, OTP configuration export, and system-level power-path behavior under varying input (4.35–5.5V), battery (3.6–4.545V), and load conditions - critical for wearables, medical sensors, and IoT edge devices.

Technical Context

The EVKT-MP2663 integrates two hardware modules: the EV2663-C-00A evaluation board hosting the MP2663 IC with integrated 330mΩ IN-to-SYS LDO MOSFET and 100mΩ SYS-to-BATT battery MOSFET, and the EVKT-USBI2C-02 interface providing USB-to-I²C bridging using Silicon Labs CP2112 firmware.

It supports Windows XP/7+ with .NET Framework 4.0, requires ≥22.2 MB disk space, and enables full register-level control via MPS I²C GUI v1.0 - including real-time read/write of charge voltage, current limits, timers, and thermal thresholds, with all I²C changes volatile across power cycles.

Key Specifications

Manufacturer

Monolithic Power Systems (MPS) is a fabless semiconductor company specializing in high-performance power management ICs for consumer, industrial, and automotive applications.

The EVKT-MP2663 belongs to MPS's battery management evaluation platform family, designed to accelerate adoption of digitally configurable chargers like the MP2663 by providing out-of-box I²C configurability, thermal safety validation, and power-path behavior visibility.

FAQ

What hardware components are included in the EVKT-MP2663 kit?

The kit contains one EV2663-C-00A MP2663 evaluation board, one EVKT-USBI2C-02 USB-to-I²C interface (with USB cable and ribbon cable), and access to online resources including the MP2663 datasheet, user guide, product brief, and I²C GUI software v1.0 - no additional hardware is required for basic evaluation.

Does the EVKT-MP2663 retain I²C configuration after power cycling?

No. All register modifications made via the MPS I²C GUI are volatile and reset to factory defaults (e.g., 4.095V charge voltage, 535mA fast charge current) upon power-down. For persistent settings, users must generate and submit an OTP configuration file through the GUI's "Export" function to MPS for custom part number assignment.

Which operating systems and software dependencies are required?

Windows XP, 7, 8, or 10 with .NET Framework 4.0 installed is mandatory. The MPS I²C GUI v1.0 requires ≥22.2 MB of free disk space. Driver installation for EVKT-USBI2C-02 must use the correct architecture-specific installer (x86/x64) and verify USBXpress driver version 4.0.0.0 on Windows 10.

How is power-path management validated using this kit?

The EV2663-C-00A board implements the MP2663's dual-path architecture: SYS output powers the system load while simultaneously charging the battery via the integrated 100mΩ battery MOSFET. Users can monitor real-time current sharing, input-to-SYS regulation, and battery disconnection events using GUI register reads and external multimeters on VIN, SYS, and VBATT test points.

Can the EVKT-MP2663 be used to evaluate thermal protection behavior?

Yes. The kit enables direct observation of on-die thermal limiting and PCB over-temperature protection (OTP) activation. When die temperature exceeds the threshold, the GUI shows status register bits toggling, charge current reduces progressively, and the IC enters shutdown - recovery occurs automatically once temperature falls below hysteresis, visible as register reinitialization in the GUI.
