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.
