MP2639C - 2-Cell Li-Ion or Li-Polymer Switching Charger

General Description

The MP2639C is a highly integrated, flexible, switch-mode, battery-charging management device for 2-cell series Li-ion and Li-polymer batteries used in a wide range of portable applications.

The MP2639C is able to charge a 2-cell battery from a 5V adapter or USB input.

Key Features

  • include charge termination and autorecharge. To guarantee safe operation, the MP2639C 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 a programmable timer to prevent prolonged charging of a dead battery. The MP2639C is available in a QFN-26 (4mmx4mm) package.

MP2639C 2-Cell Li-Ion or Li-Polymer Switching Charger Compatible with 5V Input and Integrated, Bidirectional Charge/Discharge with Cell Balance DESCRIPTION The MP2639C is a highly integrated, flexible, switch-mode, battery-charging management device for 2-cell series Li-ion and Li-polymer batteries used in a wide range of portable applications. The MP2639C is able to charge a 2-cell battery from a 5V adapter or USB input. The MP2639C 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 MP2639C operating in step-up mode. When the 5V input is absent, the 2-cell battery voltage is discharged to the 5V output via the MP2639C working in step-down mode.
