Monolithic Power Systems Inc. EV2710-C-00A

Overview

EV2710-C-00A from Monolithic Power Systems is an evaluation board for the MP2710 single-cell Li-ion/Li-polymer linear battery charger IC, featuring integrated power path management, I²C programmability, 500mA input current limit, 1mA charge termination, and <1µA battery leakage current. It enables simultaneous system powering and battery charging from USB or AC adapter inputs in space-constrained portable devices such as Bluetooth earbuds and wearable health monitors.

For engineers reviewing the EV2710-C-00A datasheet, EV2710-C-00A pinout, EV2710-C-00A application, or EV2710-C-00A equivalent, this board provides full hardware/software validation of MP2710 configuration-including VIN regulation (3.88–5.08V), fast-charge current (8–456mA), battery regulation voltage (3.6–4.545V), UVLO threshold (2.4–3.03V), and safety timer-via Windows-based GUI and USB-to-I²C interface.

Technical Context

The EV2710-C-00A implements a complete reference design for the MP2710 WLCSP-9 IC, supporting pre-charge, constant-current (CC), constant-voltage (CV), auto-recharge, and thermal regulation modes. Its layout includes all critical passive components (C1–C7, RT1/RT2, R1) and dual-mode power routing to SYS and VBATT terminals with dedicated NTC, INT, SCL/SDA, and FET control headers.

It validates real-time I²C register access (e.g., REG0x01–REG0x0F) for configuring input current limit (50–500mA), battery UVLO (2.4–3.03V), termination current (1–31mA), and discharge current limit (400–3200mA), while maintaining <1µA battery leakage during system sleep via integrated UVLO cutoff and high-impedance mode control.

FAQ

What software is required to operate the EV2710-C-00A?

The MP2710 evaluation kit .exe software-Windows-only, downloadable from the MPS website-is required. It communicates with the board via the EVKT-USBI2C-02 USB-to-I²C adapter and provides real-time register configuration, status monitoring, and fault reporting through a graphical interface.

Does the EV2710-C-00A support battery discharge control?

Yes. The board exposes the MP2710's bidirectional power-path capability: it configures battery discharge current limit (IDSCHG) from 400 mA to 3200 mA via I²C register 0x0B, enabling controlled system power-down and load testing without external circuitry.

Can the EV2710-C-00A be used with lithium-polymer batteries?

Yes. The MP2710 IC-and thus the EV2710-C-00A board-is explicitly qualified for both single-cell Li-ion and Li-polymer chemistries, supporting adjustable battery regulation voltage (3.6–4.545 V) and under-voltage lockout (2.4–3.03 V) to match cell-specific thresholds.

Is NTC thermistor support implemented on the board?

Yes. The board includes dedicated NTC terminals (NTC, AGND) and onboard resistor RT1 (50 kΩ potentiometer) to simulate and calibrate battery temperature sensing, enabling full validation of MP2710's thermal foldback and cold/hot charge inhibit functions.

What are the default charging parameters set on the EV2710-C-00A?

The board ships with factory-default settings: VBATT_REG = 4.2 V, IIN_LIM = 500 mA, ICC = 128 mA, ITERM = 3 mA, VBATT_UVLO = 2.76 V, and VRECH = 200 mV-fully reconfigurable via I²C registers without hardware modification.

Does the board include protection features beyond charge control?

Yes. It demonstrates MP2710's integrated protections: short-circuit protection (SCP) on SYS output, thermal shutdown (configurable TJ_REG), safety timer timeout, I²C watchdog reset, and automatic battery disconnect below UVLO threshold-all observable via INT pin assertion and GUI fault reporting.
