BCT2601
I2C Controlled 1-Cell 3A Battery Charger
for High Input Voltage and NVDC Power Path Management
GENERAL DESCRIPTION
The BCT2601 is a battery charger and power path management device with integrated converter and power switches use with 1-cell Li-Ion, Li-polymer batteries. It is capable for fast charging and supports a wide input voltage range suitable for smart phones, tablets and portable systems.
The BCT2601 includes four main power switches: input reverse blocking FET (RBFET, Q1), high-side switching FET for buck or boost mode (HSFET, Q2), low-side switching FET for buck or boost mode switching (LSFET, Q3) and battery FET (BATFET, Q4).
The BCT2601 is USB 2.0 and USB 3.0 power
specifications compliant with input current and voltage regulation. It also meets USB On-The-Go (OTG) power rating specification.
The BCT2601 system voltage is regulated slightly above the battery voltage by the power path management circuit and is kept above the programmable minimum system voltage (3.5V by default).Therefore, system power is maintained even if the battery is completely depleted or removed.
The BCT2601, available in QFN-4×4-24L package, provide a very compact system solution external components and PCB area.
