Monolithic Power Systems Inc. EV2696A-Q-00B

Overview

EV2696A-Q-00B from Monolithic Power Systems is an evaluation board for the MP2696A single-cell switching battery charger IC, integrating power path management and 3A boost output. It supports I²C-controlled charge current up to 3.6A, programmable SYS output (5.05–5.25V), and operates from 4–6V input with up to 18W output power. Used in power-bank development and sub-battery system validation.

For engineers reviewing the EV2696A-Q-00B datasheet, EV2696A-Q-00B pinout, EV2696A-Q-00B application, or EV2696A-Q-00B equivalent, this board enables rapid characterization of MP2696A's I²C-configurable charging, boost conversion, thermal safety, JEITA profile tuning, and USB BC1.2 detection in real-world portable power designs.

Technical Context

The EV2696A-Q-00B implements the MP2696A QFN3×3 IC in a fully assembled, test-ready layout with accessible test points (TP1–TP16), USB-A/micro-USB connectors, and configurable jumpers (JP1/JP2). It exposes all critical analog and digital interfaces: BATT, VIN, SYS, SCL/SDA/INT, NTC, IB, DP/DM, and SW nodes.

It validates three operational modes-charge (up to 3.6A), boost (5V @ up to 3.6A, 18W), and sleep-with real-time I²C register access via included USB dongle and GUI. Input over-voltage protection (up to 16V), thermal shutdown, and SYS short-circuit protection are hardware-verified on-board.

FAQ

What is the primary function of the EV2696A-Q-00B?

This is an evaluation board-not a standalone IC-for the MP2696A battery management IC. It provides hardware access to all pins, pre-populated passive components, USB connectivity, and GUI-based I²C control to validate charging, boost conversion, thermal safety, and USB detection functionality in lab and design environments.

Does the board include the MP2696A IC?

Yes. The EV2696A-Q-00B integrates one MP2696AGQ-0000 IC in a QFN-21 (3 mm × 3 mm) package, mounted and soldered on the board per the official MPS schematic and BOM. No additional IC purchase is required to operate the evaluation platform.

Can the board be used for production?

No. It is strictly an evaluation tool: unshielded layout, non-optimized thermal relief, no conformal coating, and test-point–based routing make it unsuitable for end-product deployment. It serves only for functional verification, firmware bring-up, and parameter tuning prior to custom PCB design.

What software tools are required?

The official MPS EV2696A GUI software (Windows-only) and USB-to-I²C dongle driver must be installed. The GUI provides real-time register read/write, charge/boost parameter adjustment, fault status monitoring, and JEITA profile configuration without coding.

How is battery current measured on this board?

Via the IB pin of the MP2696A, routed to test point TP9. The IC outputs an analog voltage proportional to battery current (100 mV/A typical), enabling direct oscilloscope or ADC measurement without shunt resistor modification.

Is USB BC1.2 detection verified on this board?

Yes. The DP/DM interface (TP11/TP12) connects directly to the MP2696A's dedicated BC1.2 and non-standard adapter detection circuitry. The GUI reports detected source type (SDP/CDP/DCP), and the board supports automatic current limit adaptation based on enumeration results.
