Monolithic Power Systems mp2663 | Demoboard EV2663-C-00A

Description

The EV2663-C-00A is an evaluation board for the MP2663, a highly-integrated single-cell Li-Ion/Li- Polymer battery charger with system power path management, targeted at space limited portable applications. It takes input power from either an AC adapter or a USB port to supply the system load and charge the battery independently. The charger section features pre-charge, constant current (CC) and constant voltage (CV) regulation, charge termination and charge status. EV2663 ensures the continuous power to the system by automatically selecting the input, the battery or both to power the system. EV2663 provides system short circuit protection to prevent the Li-Ion battery from being damaged due to excessive high current. EV2663 cuts off the path between battery and system when battery UVLO to prevent the Li-Ion battery from being overly discharged. Through the I2C connector on EV2663, the customer can program the charging parameters, such as: input current limit, input voltage regulation limit, charging current, battery regulation voltage, and battery UVLO.
