Monolithic Power Systems Inc. EVKT-MP2790-0002

Overview

EVKT-MP2790-0002 from Monolithic Power Systems is an end-of-life evaluation kit designed to demonstrate the MP2790 battery management IC, supporting 7–10-cell Li-ion/Li-polymer battery packs with SPI interface, 15-bit cell voltage ADC (<5mV error), 16-bit current sensing (<±0.5% error), and integrated high-side MOSFET driver for up to 70A discharge control in portable power tools and e-bikes.

For engineers reviewing the EVKT-MP2790-0002 datasheet, EVKT-MP2790-0002 pinout, EVKT-MP2790-0002 application, or EVKT-MP2790-0002 equivalent, this kit enables rapid validation of MP2790's AFE accuracy, configurable protection thresholds, passive cell balancing (58mA/cell), MTP/OTP programming flow, and thermal shutdown recovery behavior under real pack voltage (18–55V) and temperature conditions.

Technical Context

The EVKT-MP2790-0002 implements a hardware-based SPI communication path between host PC and MP2790 IC via EVKT-USBSPI-00 interface, enabling register-level configuration of overvoltage/undervoltage thresholds, short-circuit response timing, coulomb counting calibration, and NTC thermistor compensation tables.

It integrates EV2790-0002-FP-00A evaluation board with full analog front-end signal conditioning, isolated HV/LV GPIOs, dedicated thermistor inputs, open-wire detection circuitry, and persistent dead-battery flag reporting - all operating within 14cm × 9.6cm PCB footprint and requiring Windows 7+ with ≥25.6MB free space for GUI software.

FAQ

Is EVKT-MP2790-0002 still in active production?

No. EVKT-MP2790-0002 has reached End of Life per MPS documentation dated July 2023 and is superseded by EVKT-MP2790-0000, which uses I²C interface and EV2790-0000-FP-00A board. Aetrix Electronics maintains limited legacy stock for continuity support but recommends migration planning.

What hardware components are included in EVKT-MP2790-0002?

The kit contains one EV2790-0002-FP-00A evaluation board, one EVKT-USBSPI-00 USB-to-SPI interface module, one USB cable, one ribbon cable, and access to online GUI software and supplemental documents - no battery, charger, or load is included.

Can the EVKT-MP2790-0002 be used to program OTP or MTP memory on the MP2790 IC?

Yes. The kit supports full OTP and MTP configuration via the MP2790 V1.0 GUI, including exporting register sets, enabling STORE_NVM_CMD, applying 7.5V to NSHDN, and verifying NVM_STATUS - with up to three MTP writes permitted before lockout.

Does the EVKT-MP2790-0002 support real-time cell balancing verification?

Yes. The board enables manual or automatic passive cell balancing up to 58mA per cell, with GPIO-controlled external transistor drive capability and balancing status visible in GUI registers, allowing direct measurement of balancing current and voltage convergence.

What operating system and driver requirements apply to EVKT-MP2790-0002?

Windows 7 or later is required, with .NET Framework 4.0 and USBXpress driver v4.0.0.0 - older Windows-installed drivers must be manually replaced, as incompatible versions prevent SPI enumeration and cause "Disconnected" status in GUI.
