EV2665A-QB-00A Evaluation Kit 21V, 1A, Linear Charger for Single-Cell Li-Ion Batteries with Power Path Management Evaluation Board
The EV2665A-QB-00A is an evaluation board designed to demonstrate the capabilities of the MP2665A, a highly integrated, single-cell Li-ion and Li-polymer battery charger with system power path management. The MP2665A is ideal for space-constrained portable applications. It takes input power from either an AC adapter or a USB port to supply the system load and charge the battery simultaneously. It also features pre-charge, constant current (CC) fast charge, constant voltage (CV) regulation, charge termination, and auto-recharge.
The MP2665A ensures that the system is continuously powered by automatically selecting the input, the battery, or both to power the system. It provides system short-circuit protection (SCP) to prevent the Li-ion battery from being damaged due to excessively high currents.
The device also provides battery under-voltage lockout (UVLO) protection that blocks the path between the battery and the system if the battery voltage drops below the configurable UVLO threshold. This prevents the Li-ion battery from being discharged excessively.
The integrated I2C interface can configure the following charging parameters: input current limit, input voltage (VIN) regulation limit, charge current, battery regulation voltage, safety timer, and battery UVLO threshold. The MP2665A is available in a QFN-12 (2.5mmx3mm) package.
