Monolithic Power Systems Inc. EV2700-C-00A

Overview

EV2700-C-00A from Monolithic Power Systems is an evaluation board for the MP2700 26V, 1A linear battery charger IC, designed to demonstrate configurable JEITA-compliant charging, input current limiting via USBM pin, and precise charge current setting via ISET resistor network. It supports single-cell Li-ion/Li-polymer batteries with 4.2V regulation voltage and operates from 4V–6V input, with absolute max VIN of 26V.

For engineers reviewing the EV2700-C-00A datasheet, EV2700-C-00A pinout, EV2700-C-00A application, or EV2700-C-00A equivalent, this board enables rapid validation of MP2700's thermal regulation, pre-charge/fault signaling via open-drain CHG pin, NTC-based temperature window configuration, and input voltage limit (VIN_LIM) behavior under overload conditions.

Technical Context

The EV2700-C-00A implements the full functional interface of the MP2700 WLCSP-8 IC, including jumper-configurable ISET (JP1–JP3) for charge current selection from 20mA to 1A, IPRE scaling (JP4–JP5), and USBM logic control (JP6) for 100mA/500mA input current limits. It integrates fixed 10kΩ NTC pull-down (JP7) and /CHG pull-up (JP8).

Test points (TP1–TP8) provide direct access to VIN, VBATT, CHG, USBM, NTC, and EXT_PU signals, while the 6.3cm × 6.3cm PCB layout accommodates standard 0603 passives and includes dedicated connectors for battery simulator and DC power supply interfaces.

FAQ

What is the purpose of the USBM pin on the EV2700-C-00A?

The USBM pin controls the input current limit (IIN_LIM) of the MP2700 IC. On this board, JP6 selects between three states: floating (100 mA), logic high (500 mA with external 3V pull-up), or logic low (follows ISET-derived current). This enables flexible USB-compliant current limiting without firmware changes.

How do I configure the JEITA temperature profile using this board?

The EV2700-C-00A includes JP7 for fixed 10 kΩ NTC pull-down, establishing a baseline thermal reference. To implement a full JEITA profile, connect an external NTC thermistor between NTC_1 and GND, then configure temperature thresholds and charge actions via the host MCU communicating with the MP2700's I²C interface (not populated on board but supported by the IC).

Can the EV2700-C-00A be used with batteries other than 4.2V Li-ion?

No-the board is factory-configured for 4.2V regulation and lacks adjustable feedback resistors. It is intended exclusively for evaluating the MP2700's behavior with standard single-cell Li-ion or Li-polymer batteries. Altering regulation voltage requires hardware modification not supported by the board design.

What does the /CHG pin indicate, and how is it accessed?

The /CHG pin is an open-drain output that signals charge status: pulled low during active charging, high at termination, and pulsed during faults (e.g., NTC short). It is accessible via CHG_1 header and TP3 test point, allowing direct oscilloscope probing or MCU GPIO monitoring without soldering.

Is the MP2700 IC soldered to the board, and what is its package?

Yes-the MP2700GC IC is permanently mounted in WLCSP-8 (1.05 mm × 1.6 mm) package, as confirmed in the Bill of Materials. This ultra-compact chip-scale package enables minimal footprint and thermal performance validation, matching production-level assembly conditions.

Does the board support I²C communication with the MP2700?

The MP2700 supports I²C configuration of JEITA parameters, but the EV2700-C-00A does not include I²C pull-ups or dedicated headers. Users must add external 4.7kΩ pull-ups to SDA/SCL and route signals via test points or custom wiring to enable register-level control beyond jumper-based settings.
