About This Product

■Summary

The MP2639C is a highly integrated and flexible switch-mode battery charge management device for 2-cell Li-ion and Li-Polymer batteries used in a wide range of portable applications. MP2639C can charge 2-cell batteries from a 5V adapter or USB input. MP2639C can operate in three modes: charging mode, discharging mode, and sleep mode. In 2-cell applications, a 5V input charges a 2-cell battery through the MP2639C operating in step-up mode. When 5V input is not present, the 2-cell battery voltage is discharged to 5V output through MP2639C operating in step-down mode. For charging function, MP2639C automatically detects the battery voltage and charges the battery in three phases: trickle current, constant current, and constant voltage. Other features include charge termination and automatic recharging. To ensure safe operation, the MP2639C limits die temperature to a preset value of 120°C. Other safety features include input overvoltage protection (OVP), battery overvoltage protection (OVP), thermal shutdown, battery temperature monitoring, and a programmable timer to prevent long-term charging of a dead battery. The MP2639C is available in a QFN-26 (4mm x 4mm) package.

■Features and benefits

・Input voltage range from 4.0V to 5.75V ・Charges a 2-cell battery with 5V input ・USB compatible charger ・Integrated input current-based and input voltage-based power management functions ・Programmable input current and input voltage limits - Programmable charging current up to 2.5A for 2-cell applications ・8.4V feedback voltage with 0.5% accuracy ・Programmable discharge current up to 5.0A ・Negative temperature coefficient pin for temperature monitoring ・No-load shutdown and push button turn-on in discharge mode ・Backup protection with programmable timer ・Discharge mode load trace compensation ・Temperature control and thermal shutdown ・Prevention of reverse leakage current of internal battery ・Integrated short circuit protection (SCP) in both charging and discharging modes ・4 LED battery level and status indicators
