Monolithic Power Systems Inc. EVKT-MP2664

Overview

EVKT-MP2664 from Monolithic Power Systems is an evaluation kit for the MP2664 - a single-cell Li-ion/Li-polymer battery charger IC with I²C-controlled power-path management, 500mA fast-charge capability, 3.6V–4.545V battery regulation, and QFN package integration. It enables rapid validation of battery charging and system power routing in portable devices such as Bluetooth headsets, wearables, and medical sensors.

For engineers reviewing the EVKT-MP2664 datasheet, EVKT-MP2664 pinout, EVKT-MP2664 application, or EVKT-MP2664 equivalent, this kit provides full GUI-driven configuration of charge current (8–535mA), input current limit (85–455mA), battery UVLO threshold, and discharge current (400–3200mA) via USB-to-I²C interface under Windows XP/7+.

Technical Context

The EVKT-MP2664 implements hardware-based power-path control using a 100mΩ battery-to-system switch and low-dropout input-to-system regulator, enabling simultaneous charging and system operation without battery stress. It supports pre-charge, constant-current (CC), and constant-voltage (CV) charging phases with automatic termination and real-time status reporting via I²C.

On-chip protections include system short-circuit protection (SCP), programmable battery under-voltage lockout (UVLO), and input voltage regulation set to VBATT + 400mV - ensuring safe operation across 4.35V–5.5V input range and preventing Li-ion over-discharge.

FAQ

What components are included in the EVKT-MP2664 kit?

The kit includes the EV2664 evaluation board (EV2664-G-00A), EVKT-USBI2C-02 interface (USB-to-I²C adapter + ribbon cable), USB flash drive with MP2664 GUI V1.1 software, and access to online resources including datasheet, user guide, and product brief.

Does the EVKT-MP2664 require external power supplies or batteries to operate?

Yes - it requires an external DC power supply set between 4.35V and 5.5V to power the board, and a single-cell Li-ion or Li-polymer battery (3.0V–4.5V) for charging validation. No additional passive components are needed for basic functionality.

Can the EVKT-MP2664 be used to evaluate multiple battery chemistries?

No - it is specifically designed and calibrated for single-cell Li-ion and Li-polymer batteries only. The UVLO threshold, CV voltage range, and charge termination logic are optimized for these chemistries and not configurable for NiMH or LiFePO₄.

Is GUI software required to configure the MP2664 on the EVKT-MP2664?

Yes - all programmable parameters (fast-charge current, input current limit, battery UVLO, discharge enable) are controlled exclusively via the Windows-based GUI using the included USB-to-I²C interface; no jumpers or DIP switches are provided for manual configuration.

What protection features are implemented on the EVKT-MP2664 evaluation board?

The board implements full MP2664 on-die protections: system short-circuit protection (SCP), battery under-voltage lockout (UVLO), thermal shutdown, and input overvoltage clamp. These are active during both charging and system-power modes without external circuitry.
