EV2667-G-00A Evaluation Board of 1A Linear Charger with Power Path Management for Single-Cell Li-Ion Battery in QFN Package DESCRIPTION FEATURES The EV2667-G-00A is an evaluation board for Fully Autonomous Charger for Single-Cell the MP2667, a highly-integrated single-cell Li- Li-Ion/Polymer Batteries Ion/Li-Polymer battery charger with system Current Limit for USB Port power path management, targeted at space Complete Power Path Management for limited portable applications. It takes input power Simultaneously Powering the System and from either an AC adapter or a USB port to Charging the Battery supply the system load and charge the battery 0.5% Charging Voltage Accuracy independently. The charger section features 13V Maximum Voltage for the Input Source constant current pre charge (PRE.C), constant 2 I C Interface for Setting charging Parameters current fast charge (CC), constant voltage (CV) and Status Reporting regulation, charge termination, and charge status. Robust Charging Protection Including Battery Temperature Monitor and Programmable EV2667 ensures the continuous power to the system by automatically selecting the input, the Timer battery or both to power the system. Battery Disconnection Function EV2667 provides system short circuit protection to APPLICATIONS prevent the Li-Ion battery from being damaged due Wearable devices to excessive high current. Smart Handheld Devices EV2667 cuts off the path between battery and Fitness Accessories system when battery UVLO to prevent the Li-Ion Smart Watches battery from being overly discharged. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Through the I2C connector on EV2667, the Quality Assurance.
