The EV2665A-QB-00A is an evaluation board designed to demonstrate the capabilities of Monolithic Power Systems’ 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 adaptor 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 regulation limit, charge current, battery regulation voltage, safety timer and battery UVLO threshold. The MP2665A is available in a QFN-12 (2,5 x 3 mm) package.
