Description
The Future of Analog IC Technology MP2639A 2-Cell Li-Ion or Li-Polymer Switching Charger Compatible with 5V Input and Integrated, Bidirectional Charg.
The MP2639A is a highly integrated, flexible, switch-mode, battery-charging management device for 2-cell series Li-ion and Li-polymer batteries used i.
Features
* include charge termination and autorecharge. To guarantee safe operation, the MP2639A limits the die temperature to a preset value of 120°C. Other safety features include input overvoltage protection (OVP), battery over-voltage protection (OVP), thermal shutdown, battery temperature monitoring, and
Applications
* The MP2639A is able to charge a 2-cell battery from a 5V adapter or USB input. The MP2639A can work in three modes: charge mode, discharge mode, and sleep mode. In 2-cell applications, the 5V input charges the 2-cell battery via the MP2639A operating in step-up mode. When the 5V input is absent, th
