About This Product

■Summary

The MP2615 is a high efficiency switch-mode battery charger suitable for 1-cell to 2-cell Li-Ion or Li-Polymer applications. The MP2615 can provide a programmable 2A charging current through an accurate sense resistor over the entire input range. The MP2615 uses two control loops to regulate charging current and total battery voltage to achieve highly accurate constant current (CC) and constant voltage (CV) charging. Constant Off-Time (COT) mode control allows operation at up to 99% duty cycle to keep charging current at a relatively high level at all times when the battery voltage is close to the input voltage. Battery temperature and state of charge are constantly monitored during each charging cycle. Two status monitoring output pins are provided to indicate battery charging status and input power status. The MP2615 also features internal anti-reflux protection. The MP2615 is available in a QFN-16 (3mm x 3mm) package.

■Features and benefits

・Operating input voltage from 4.75V to 18V - Operates at up to 99% duty cycle ・Programmable charging current up to 2A ・±0.75% total battery voltage accuracy ・4.1V/cell and 4.2V/cell selection for full battery voltage ・Fully integrated power switch ・Inner loop compensation ・No external backflow prevention diode required - Preconditioning of fully depleted batteries ・Charging operation indicator ・Programmable safety timer ・Thermal shutdown protection ・Cycle-by-cycle overcurrent protection ・Battery temperature monitoring and protection

■Available product numbers

・MP2615GQ-P MP2615GQ-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
