MP2639B - 1S Cell Li-ion or Li-polymer Switching Charger

General Description

The MP2639B is a highly integrated, flexible switch-mode battery charging management device for a single-cell Li-ion and Li-Polymer battery used in a wide range of portable applications.

The MP2639B works in three modes: charge mode, discharge mode, and sleep mode.

Key Features

  • include charge termination and autorecharge. When the input is absent, the MP2639B can provide a wide boost voltage to IN by adjusting the feedback voltage at FB. When working with the PD controller, the MP2639B can support a USB PD standard output voltage level. To guarantee safe operation, the MP2639B limits the die temperature to a preset value of 120ºC. Other safety features include input overvoltage protection, battery over-voltage protection, thermal shutdown, battery temperature monitorin.

MP2639B 1S Cell Li-ion or Li-polymer Switching Charger Compatible with Wide Input Range and Integrated Programmable OTG DESCRIPTION The MP2639B is a highly integrated, flexible switch-mode battery charging management device for a single-cell Li-ion and Li-Polymer battery used in a wide range of portable applications. The MP2639B works in three modes: charge mode, discharge mode, and sleep mode. (See Table 1) When the input power supply is available, the MP2639B operates as a switching charger to charge a 1S battery from a wide input power range of 5V to 16V, which can cover a USB PD voltage level. The MP2639B automatically detects the battery voltage and charges the battery in three phases: pre-charge, constant charge, and constant voltage charge.
