Monolithic Power Systems Inc. EV2696B-Q-00A

Overview

EV2696B-Q-00A from Monolithic Power Systems is an evaluation board for the MP2696B single-cell switch-mode battery charger IC with integrated power-path management, supporting charge (up to 3.6A), boost (5V/3A SYS output), and sleep modes, configurable via I²C, and validated for power bank and sub-battery applications.

For engineers reviewing the EV2696B-Q-00A datasheet, EV2696B-Q-00A pinout, EV2696B-Q-00A application, or EV2696B-Q-00A equivalent, this board enables rapid validation of MP2696B's I²C-configurable charge regulation (4.2V), input current limit (0.5A), SYS output (5.15V), peak inductor current (6.5A), and safety features including JEITA profiling and thermal shutdown.

Technical Context

The EV2696B-Q-00A implements the MP2696B QFN-21 (3mm×3mm) IC in a fully assembled, test-ready layout with dedicated test points (TP1–TP16), micro-USB input (P2), USB-A output (P1), and SYS/IB/NTC monitoring interfaces. It supports real-time parameter tuning via SCL/SDA/GND/INT I²C connector and includes on-board 10mΩ current-sense resistor (RS1) and 1μH power inductor (L1).

Board-level design integrates all critical passive components per MPS reference layout: 22μF input capacitor (C8), dual 10μF output capacitors (C1/C2), 2.2μF battery-side capacitor (C9), and magnetic bead (L2) for EMI suppression. Default jumper settings (JP1 installed, JP2 installed) enable NTC divider and I²C pull-ups.

FAQ

What is the primary function of the EV2696B-Q-00A evaluation board?

The EV2696B-Q-00A is a fully assembled hardware platform that demonstrates the MP2696B IC's capabilities as a single-cell switch-mode charger with integrated power-path management and bidirectional boost conversion. It enables engineers to validate charge profiles, SYS output regulation, I²C configuration, and safety responses without designing custom PCBs.

Does the board support battery simulation and real-cell testing?

Yes-the board accepts both real Li-ion/Li-polymer cells (via TP1/BATT and TP2/GND) and programmable battery simulators (e.g., set to 3.8 V/5 A). The on-board 10 mΩ sense resistor (RS1) and IB pin routing allow accurate battery current measurement during charge and discharge cycles.

How is I²C communication established with the MP2696B on this board?

I²C communication uses the SCL/SDA/INT/GND header (labeled on silkscreen), which connects directly to the MP2696B's pins 15, 16, 14, and 11. Users must install the MPS USB-to-I²C driver and use the official GUI software to configure registers, monitor status flags, and log faults in real time.

What safety protections are implemented and how are they verified on this board?

The board implements MP2696B's native protections: input OVP (16 V max), thermal shutdown (125°C threshold), JEITA-compliant temperature-based charge control, charge safety timer, and SYS OCP/SCP. These are verified using the GUI's fault register readback and by inducing controlled overloads or temperature excursions during testing.

Can the EV2696B-Q-00A be used to evaluate BC1.2 and non-standard adapter detection?

Yes-the board routes DP/DM pins (TP11/TP12) from the MP2696B to accessible test points and includes P1 (USB-A) and P2 (micro-USB) connectors. The IC's built-in BC1.2 and proprietary adapter detection logic is active by default and can be monitored via I²C register reads or INT pin assertion.

Are all passive components populated, and is the board RoHS-compliant?

All bill-of-materials components listed in Rev. 1.0 documentation are factory-populated, including Murata/TDK/Yageo passives, Würth magnetics, and the MP2696BGQ-0000 IC. The board meets RoHS Directive 2011/65/EU and is halogen-free and lead-free per MPS green policy.
