Beschreibung

The EV2639B-R-00A is the reference design board for MP2639B, a highly-integrated, flexible switch-mode battery charge management for a single-cell Li-ion and Li-Polymer battery used in a wide range of applications. The demo board shows two operating modes—charge mode and boost mode. When input power is present, the board charges a single-cell battery with a programmable charge current up to 5A. In the absence of an input source, the board switches to boost mode through the PB pin control to power the VH pin from the battery with a current up to 3A. The evaluation board provides 4-LED to indicate the voltage based fuel gauge and distinguish charge mode from boost mode. To guarantee the safe operation, the EV2639B-R-00A has input-over-voltage protection, battery over-voltage protection, thermal shutdown, battery-temperature monitoring, and a programmable timer to prevent prolonged charging of a dead battery.
