Monolithic Power Systems Inc. EVKT-MP2672

Overview

EVKT-MP2672 from Monolithic Power Systems is an evaluation kit for the MP2672 battery management IC, enabling engineers to validate 2-cell Li-ion charging, discharging, and NVDC power path management under host-controlled or standalone operation. It supports 4.5V–6.0V input, delivers up to 2A charge current at 8.4V, and integrates I²C programmability, cell balancing, JEITA-compliant temperature monitoring, and thermal regulation.

For engineers reviewing the EVKT-MP2672 datasheet, EVKT-MP2672 pinout, EVKT-MP2672 application, or EVKT-MP2672 equivalent, this kit provides hands-on validation of MP2672's fast-charge sequencing, OTP configuration workflow, real-time register read/write via GUI, and system-level behavior under load, battery, and thermal stress conditions.

Technical Context

The EVKT-MP2672 comprises two hardware modules: the EV2672-D-01A evaluation board hosting the MP2672 IC in QFN-24 package, and the EVKT-USBI2C-02 interface dongle providing USB-to-I²C bridge functionality. The board implements full NVDC architecture with independent SYS and BATT rails, programmable input voltage limit, and cycle-by-cycle MOSFET over-current protection.

Operation spans dual modes: standalone (with LED indicators and auto-recharge) and host-controlled (via I²C GUI). All runtime register changes are volatile; OTP programming requires MPS FAE support and produces non-modifiable firmware images. JEITA NTC monitoring enables compliant charge profile throttling across temperature zones.

FAQ

Does EVKT-MP2672 include the MP2672 IC?

Yes. The EV2672-D-01A board included in the kit integrates the MP2672 IC in a QFN-24 package. The IC is pre-soldered and fully functional out-of-box, with all necessary passive components and layout optimized per MPS reference design guidelines.

Can I retain I²C configuration after power cycling?

No. All I²C register modifications are volatile and reset to factory defaults upon power-down. Persistent settings require OTP programming, which must be performed by MPS Field Application Engineers using exported configuration files and proprietary tools.

What software is required to operate the kit?

The MP2672 V1.0 GUI software is mandatory. It runs on Windows XP or later, requires .NET Framework 4.0, and communicates with the EV2672-D-01A board via the EVKT-USBI2C-02 dongle. No additional drivers are needed beyond the included USBXpress v4.0.0.0 installer.

Is cell balancing active by default?

Yes. The integrated cell balancing circuit activates automatically when the cell voltage mismatch exceeds the factory-preset threshold (configurable via OTP), ensuring safe and balanced charging of 2S Li-ion stacks without external balancer ICs or discrete FETs.

What happens if input voltage drops below 4.5V?

The MP2672 enters UVLO state: charging halts immediately, and the system switches to battery-only operation. The GUI reflects "No Supply" status, and no register writes succeed until VIN rises above the UVLO rising threshold (~4.55V typical).

Does the kit support JEITA temperature profiling?

Yes. The NTC pin accepts a standard 10kΩ thermistor, and the MP2672 implements JEITA-compliant charge current/voltage derating across five temperature zones (Cold, Cool, Normal, Warm, Hot), as defined in the MP2672 datasheet.
