Monolithic Power Systems Inc. EVKT-MP2790-0000

Overview

EVKT-MP2790-0000 from Monolithic Power Systems is a complete evaluation kit for the MP2790 battery management AFE IC, designed to validate 7–10-cell lithium-ion/polymer battery pack monitoring and protection in industrial, medical, and portable energy storage systems. It includes the EV2790-0000-FP-00A evaluation board, EVKT-USBI2C-02 USB-to-I²C interface, ribbon/USB cables, and GUI software supporting real-time register configuration, cell voltage/current measurement, and configurable fault response.

For engineers reviewing the EVKT-MP2790-0000 datasheet, EVKT-MP2790-0000 hardware setup, EVKT-MP2790-0000 GUI operation, or EVKT-MP2790-0000 ordering options, this kit delivers full functional validation of the MP2790's analog front-end accuracy, I²C communication integrity, MOSFET driver control, and passive cell balancing-enabling rapid prototyping of BMS firmware and safety-critical threshold tuning before production design-in.

Technical Context

The EVKT-MP2790-0000 implements a hardware-software co-validation platform centered on the MP2790 IC, which integrates a 15-bit ADC for cell voltage (<5 mV error at 25°C), a 16-bit ADC for pack current (<±0.5% error), and synchronized sampling for impedance sensing. Its architecture supports dual-domain power path control via integrated high-side MOSFET drivers capable of 70 A DC with external N-channel FETs.

Configuration is performed through MPS GUI v1.0 over I²C, enabling read/write access to volatile registers (reset on power cycle) and non-volatile MTP memory (programmable twice post-factory). The kit validates critical BMS functions including charge/discharge OCP/SCP, cell UVP/OVP, thermal protection across four NTC inputs, and open-wire detection-all configurable per application safety requirements.

FAQ

What is the difference between EVKT-MP2790-0000 and EVKT-MP2790-0002?

EVKT-MP2790-0000 uses I²C communication via the EVKT-USBI2C-02 interface, while EVKT-MP2790-0002 uses SPI via EVKT-USBSPI-00. The latter is End-of-Life and superseded by EVKT-MP2790-0000; only the -0000 variant is actively supported and stocked.

Does the evaluation kit retain configuration after power-down?

No-register settings written via I²C are volatile and reset on power cycle. Only MTP memory retains values across power cycles, and it is programmable only twice post-factory. OTP settings are factory-programmed and immutable.

Can the EVKT-MP2790-0000 evaluate all MP2790 protection features?

Yes-it fully validates charge/discharge OCP/SCP, cell and pack UVP/OVP, die and cell temperature protection, open-wire detection, and persistent dead-battery flag behavior using real-world voltage/current stimuli and GUI-triggered fault injection.

Is external hardware required beyond the kit contents?

No-the kit includes all necessary components: EV2790-0000-FP-00A board, EVKT-USBI2C-02 interface, USB/ribbon cables, and GUI software. Users supply only the battery pack (18–55 V), charger/load, and Windows PC with USB port and 25.6 MB free space.

How is cell balancing validated on this kit?

The kit supports passive balancing up to 58 mA per cell via onboard FETs and allows connection of external balancing transistors. Balancing mode (auto/manual), current limit, and cell selection are configured and verified in real time using the GUI's Balancing Control tab and voltage trend logging.

What thermal management features does the kit demonstrate?

It validates die temperature shutdown and recovery, cell-level low/high-temperature protection using four dedicated NTC inputs, and thermal fault interrupt generation-all configurable in the GUI under Temperature Settings and observable in real-time status registers.
