Monolithic Power Systems Inc. EV2663-C-00A

Overview

EV2663-C-00A from Monolithic Power Systems is an evaluation board for the MP2663 linear battery charger IC, designed to validate power path management and I²C-programmable charging of single-cell Li-ion/Li-polymer batteries. It supports 4.35–5.5V input, delivers up to 535mA charge current with 0.5% voltage accuracy, and enables simultaneous system powering and battery charging in space-constrained wearable and smart handheld devices.

For engineers reviewing the EV2663-C-00A datasheet, EV2663-C-00A pinout, EV2663-C-00A application, or EV2663-C-00A equivalent, this board provides full access to programmable parameters-including input current limit (85–455mA), battery regulation voltage (3.6–4.545V), UVLO threshold (2.4–3.1V), pre-charge current (6–27mA), and discharge current limit (400–3200mA)-via its onboard I²C interface and USB-to-I²C communication kit.

Technical Context

The EV2663-C-00A implements a complete reference design for the MP2663GC-0000 WCSP-packaged charger IC, integrating autonomous pre-charge, constant-current/constant-voltage regulation, and battery disconnect on under-voltage lockout. It features dual power sources (USB or AC adapter), real-time I²C register access, and hardware-level protections including system short-circuit and thermal monitoring.

Board-level implementation includes 1206/0805/0603 passive components optimized for low-noise operation, a Micro-B USB connector for host interface, and dedicated test points for VIN, BATT, SYS, AGND, and INT signals-enabling direct probing of charge status, fault reporting, and power path selection behavior without soldering or modification.

FAQ

What power sources can be used with the EV2663-C-00A?

The board accepts input from either a 5 V USB port or an external DC adapter within 4.35–5.5 V. It automatically selects between input source and battery to power the system load, enabling seamless transition during charging and discharging without interruption to connected peripherals or microcontrollers.

Does the EV2663-C-00A support battery temperature monitoring?

Yes-it includes provisions for NTC thermistor connection (RT1 and RT2 footprints) and supports programmable thermal regulation via I²C registers. The default configuration disables NTC monitoring, but enabling EN_PCB OTP allows PCB-level overtemperature protection independent of battery thermistor input.

How is charging parameter configuration performed?

Using the included MP2663 Evaluation Kit software on Windows, users connect via a USB-to-I²C communication kit to configure all key parameters-including input current limit, charge current, battery regulation voltage, UVLO threshold, pre-charge current, and safety timer-through real-time register read/write operations without hardware changes.

What protection features are implemented on the board?

The board inherits all MP2663 IC-level protections: battery UVLO cutoff, system short-circuit detection, programmable charge termination, thermal foldback, and I²C watchdog timer. Hardware-level safeguards include current-sense resistors, ceramic capacitor filtering per MPS layout guidelines, and isolated GND planes for noise immunity.

Is the EV2663-C-00A RoHS-compliant and lead-free?

Yes-both the MP2663GC-0000 IC and all populated passive components meet RoHS, lead-free, and halogen-free requirements per MPS quality assurance standards. Full compliance documentation, including material declarations and test reports, is available on the Monolithic Power Systems website.

Can the board be used for production-level testing?

No-it is strictly an evaluation platform intended for functional validation, firmware development, and parameter tuning. While it demonstrates full MP2663 capability, its layout, component selection, and lack of conformal coating or environmental qualification make it unsuitable for end-product deployment or reliability stress testing.
