Monolithic Power Systems Inc. EVKT-MP2787-0000

Overview

EVKT-MP2787-0000 from Monolithic Power Systems is a complete evaluation kit for the MP2787 battery management AFE IC, enabling rapid validation of 7–16-cell lithium-ion/polymer battery pack monitoring, impedance sensing, and cell balancing in lab and development environments.

For engineers reviewing the EVKT-MP2787-0000 datasheet, EVKT-MP2787-0000 hardware setup, EVKT-MP2787-0000 GUI configuration, or EVKT-MP2787-0000 software interface compatibility, this kit delivers full I²C-based register access, real-time voltage/current/temperature measurement, and MTP-programmable alarm thresholds with traceable calibration and open-wire detection.

Technical Context

The EVKT-MP2787-0000 integrates the EV2787-0000-FP-00A evaluation board with EVKT-USBI2C-02 USB-to-I²C interface and GUI software, forming a closed-loop test system for the MP2787's 15-bit cell voltage ADC (<5 mV error), 16-bit current sensing (<±0.5% error), and hardware-configurable overvoltage/undervoltage/overcurrent alarms.

It supports configurable cell count (7–16 series), passive balancing up to 58 mA per cell, integrated 3.3 V/5 V LDOs, and thermistor inputs for up to four NTC sensors - all validated within a 10.4 cm × 9.6 cm PCB footprint operating across 18 V–75.2 V pack voltage range.

FAQ

What interfaces does the EVKT-MP2787-0000 support for host communication?

The EVKT-MP2787-0000 uses the EVKT-USBI2C-02 module to provide I²C communication between the PC and the MP2787 IC. It requires no external level-shifting and operates natively at 3.3 V logic levels, with 8-bit CRC enabled by default in GUI configuration mode.

Does the kit retain configuration after power cycle?

No - all register changes made via I²C during GUI operation are volatile and reset on power-down. Only configurations written to OTP or MTP memory persist across cycles, and MTP writes are limited to two successful programming events post-factory.

Can the EVKT-MP2787-0000 evaluate both MP2787-0000 and MP2787-0002 variants?

No - EVKT-MP2787-0000 is hardware-matched to the MP2787-0000 variant and uses I²C interface. The MP2787-0002 variant requires EVKT-MP2787-0002 with SPI interface (EVKT-USBSPI-00); pinouts and register maps differ between the two IC versions.

What battery configurations can be tested with this kit?

The kit supports 7–16 series-connected cells with full voltage monitoring per cell, open-wire detection on all channels, and hardware-configurable UV/OV thresholds. Cell count is set in GUI Configuration tab and written to the IC's volatile registers before measurement.

How is cell balancing validated on the EVKT-MP2787-0000?

Passive balancing is verified using onboard 58 mA per-cell FETs controlled via GUI-enabled manual/auto modes. Balancing status, current, and temperature derating are visible in real time; external transistor drive capability is accessible via dedicated gate drive pins on the EV2787-0000-FP-00A board.

Is GUI software included and how is it installed?

Yes - the MP2787 GUI v1.0 is included as downloadable software. Installation requires Windows 7+, .NET Framework 4.0, and 25.6 MB free space. The installer is extracted from "Programming tool MP2787 V1.0", then executed with administrator privileges to deploy drivers and UI components.
