Monolithic Power Systems Inc. EVKT-MP2722

Overview

EVKT-MP2722 from Monolithic Power Systems is an evaluation kit for the MP2722 I²C-controlled, single-cell, 5A NVDC buck charger with USB Type-C dual-role power (DRP) detection. It enables rapid validation of battery charging, source-mode boost, and USB-C DRP functionality across 4V–16V input, 4.2V battery regulation, and configurable 750kHz–1.5MHz switching frequency - used in portable electronics design labs and power architecture prototyping.

For engineers reviewing the EVKT-MP2722 datasheet, EVKT-MP2722 setup procedure, EVKT-MP2722 GUI software integration, or EVKT-MP2722 hardware compatibility with Windows XP/7+, this page delivers verified configuration steps, interface specifications, and functional boundaries - including USB-to-I²C communication requirements, EVB size (6.3cm × 6.3cm), and OTP programming workflow.

Technical Context

The EVKT-MP2722 comprises two physical units: the EV2722-RH-00A evaluation board hosting the MP2722 QFN-22 IC, and the EVKT-USBI2C-02 USB-to-I²C interface enabling register-level control via MPS I²C GUI software. It supports both I²C runtime reconfiguration and one-time programmable (OTP) parameter storage.

Hardware operation requires strict sequencing: PC connection → EVB-to-USBI2C ribbon cable attachment → VIN (4–16V) application. The kit implements full safety supervision - including JEITA thermal profiling, die temperature regulation (60°C–120°C), charge timers, and watchdog logic - all observable and adjustable through the GUI.

Key Specifications

The EVKT-MP2722 belongs to MPS's evaluation platform product line, designed specifically to accelerate development of portable, battery-powered systems using their MP2722 NVDC charger - targeting wearables, tablets, and USB-C-enabled consumer electronics.

FAQ

What hardware components are included in the EVKT-MP2722 kit?

The EVKT-MP2722 kit contains the EV2722-RH-00A evaluation board, the EVKT-USBI2C-02 USB-to-I²C interface module, one USB cable, one 3-pin or 10-pin ribbon cable, and access to the MPS I²C GUI software and documentation. No external power supply or battery is included - users must provide 4V–16V input and a compatible single-cell Li-ion source.

Can configuration changes made via the I²C GUI be retained after power-down?

No - all I²C register modifications are volatile and reset to factory defaults upon power cycle. Permanent configuration requires OTP programming: users export settings via the GUI's "OTP View", submit the generated text file to an MPS FAE, and receive a custom OTP code for final device programming - which cannot be altered post-burn.

What safety features does the EVKT-MP2722 demonstrate through the MP2722 IC?

The kit demonstrates full MP2722 safety architecture: JEITA-compliant NTC-based thermal profiling, die temperature regulation (configurable 60°C–120°C), pre-charge and full-charge timers, watchdog timer, over-voltage protection thresholds, and ultra-low 8.5μA shipping mode discharge - all accessible and adjustable via the GUI interface.

Is the EVKT-MP2722 compatible with operating systems other than Windows?

No - the official MPS I²C GUI software and USBXpress drivers are validated only on Windows XP, 7, 8, 10, and 11. Linux or macOS users require virtualization or third-party I²C host tools; MPS does not provide native drivers or GUI builds for non-Windows platforms per the Rev. 1.0 User Guide.

How is USB-C DRP functionality tested using this evaluation kit?

The EVKT-MP2722 enables DRP testing by configuring CC1/CC2 pin behavior via I²C registers to enter Try.SNK or Try.SRC modes. Users connect USB-C cables to the EVB's CC pins and monitor role negotiation, VBUS sourcing/sinking, and state transitions using the GUI's real-time register readout and status flags - without requiring external PD controllers.

What is the purpose of the EVKT-USBI2C-02 module in this kit?

The EVKT-USBI2C-02 serves as the physical bridge between the host PC and the MP2722 IC's I²C bus. It converts USB commands into I²C transactions, enabling register-level control, live telemetry, and OTP export. Its firmware supports MPS Virtual Bench Pro and is required for all GUI-based evaluation - no direct UART or SWD interface is provided on the EV2722-RH-00A board.
