Monolithic Power Systems Inc. EV2610ER-00A

Overview

EV2610ER-00A from Monolithic Power Systems is an evaluation board for the MP2610 switching Li-Ion battery charger IC, supporting 1- or 2-cell configurations with up to 2A programmable charge current, 1.1MHz fixed-frequency operation, ±0.75% battery voltage regulation accuracy, and integrated thermal/battery temperature protection - used for rapid validation of high-efficiency charging in portable power systems.

For engineers reviewing the EV2610ER-00A datasheet, EV2610ER-00A pinout, EV2610ER-00A application, or EV2610ER-00A equivalent, this board enables functional verification of MP2610-based charger designs including input supply monitoring, CC/CV charge sequencing, preconditioning for deeply discharged batteries, and real-time status indication via dual LEDs.

Technical Context

The EV2610ER-00A implements the MP2610 IC in a fully assembled, tested layout with QFN16 footprint, supporting 5.5–24V input and delivering regulated 4.2V (1-cell) or 8.4V (2-cell) output. It uses two independent control loops for precise constant-current (CC) and constant-voltage (CV) charging phases.

Board-level features include on-board 4.7µH power inductor (Cooper DR73-4R7-R), 100mΩ precision current-sense resistor (Vishay WSL2512), NTC thermistor interface, and dual-color LED status indicators driven from VREF33 - all configured per MP2610 Rev. 1.1 reference design guidelines.

FAQ

What is the default battery voltage setting on the EV2610ER-00A?

The board is preset to 4.2V output for single-cell Li-Ion operation. To configure for two-cell (8.4V) charging, the Cell pin must be connected to VREF33 per the Quick Start Guide - no resistor changes or firmware updates are required.

How is charge current programmed on this evaluation board?

Charge current is set by the 100mΩ sense resistor RS1. Using the formula I_CHG = 200mV / R_S1, the default value yields 2A. Replacing RS1 with a different resistance (e.g., 200mΩ for 1A) recalibrates full-scale current without circuit modification.

Does the board support battery temperature monitoring?

Yes - it includes a 10kΩ NTC thermistor (Yageo RC0603FR-0710KL) connected to the MP2610's TS pin, enabling battery temperature sensing and automatic charge suspension if thresholds are exceeded, per MP2610's built-in thermal protection logic.

What do the green and red LEDs indicate during operation?

LED1 (green) illuminates when valid input voltage is present and within operating range. LED2 (red) lights during active charging and turns off upon battery full termination, fault condition, or no battery connection - providing immediate visual state feedback without external instrumentation.

Can the EV2610ER-00A be used with non-Li-Ion chemistries?

No - the MP2610 IC and board design are optimized exclusively for Li-Ion/Li-Polymer battery profiles, including CC/CV regulation, 4.2V/8.4V termination voltages, and NTC-based temperature limits aligned to lithium chemistry safety requirements.

Is the MP2610 IC soldered to the board or socketed?

The MP2610 is permanently mounted in QFN16 package (U1) using standard reflow soldering - not socketed. The board is intended for functional evaluation and reference design replication, not IC replacement or swapping.
