EV2667-G-00A

The EV2667-G-00A is an evaluation board for the MP2667, 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 constant current pre charge, constant current fast charge, constant voltage regulation, charge termination and charge status. EV2667 ensures the continuous power to the system by automatically selecting the input, the battery or both to power the system. EV2667 provides system short circuit protection to prevent the Li-Ion battery from being damaged due to excessive high current. EV2667 cuts off the path between battery and system when battery UVLO to prevent the Li-Ion battery from being overly discharged.

• Fully autonomous charger for single-cell li-ion/polymer batteries
• Current limit for USB port
• Complete power path management for simultaneously powering the system and charging the battery
• ±0.5% charging voltage accuracy
• 13V maximum voltage for the input source
• I2C interface for setting charging parameters and status reporting
• Robust charging protection including battery temperature monitor and programmable timer
• Battery disconnection function
