The EV2639A-R-00B is the reference design board for MP2639A, a highly-integrated, flexible switch-mode battery charge management for 2-cell series Li-ion and Li-Polymer battery used in a wide range of applications.

The demo board works in charge mode and allows management of system and battery power based on the state of the input.

When input power is present, the board charges a 2-cell series battery with 2.5A charge current.

The evaluation board provides 4-LED drivers to achieve the voltage based fuel gauge indication.

To guarantee safe operation, the EV2639A-R-00B has input-over-voltage protection, battery over-voltage protection, thermal shutdown, battery-temperature monitoring, and a charge timer to prevent prolonged charging a dead battery.
