Integrated Circuit BQ25606RGER Stand Alone 1cell 3A Fast Charger With High Input Voltage

Product Description

The BQ25606 is a highly-integrated standalone 3.0-A switch-mode battery charge management and system power path management device for single cell Li-ion and Li-polymer batteries. The solution is highly integrated with input reverse-blocking FET (RBFET, Q1), high-side switching FET (HSFET, Q2), low-side switching FET (LSFET, Q3), and battery FET (BATFET, Q4) between system and battery. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery life during discharging phase.

The BQ25606 features fast charging with high input voltage support for a wide range of standalone chargers and portable devices. Its input voltage and current regulation deliver maximum charging power to the battery. It also integrates a bootstrap diode for the high-side gate drive for simplified system design.

The device supports a wide range of input sources, including standard USB host port, USB charging port, and USB compliant high voltage adapter. The device sets the default input current limit based on the built-in USB interface. The device is compliant with the USB 2.0 and USB 3.0 power specs with input current and voltage regulation. When the built-in USB interface identifies the input adaptor is unknown, the input current limit of the device is determined by the ILIM pin setting resistor value. The device also meets the USB On-the-Go (OTG) operation power rating specification by supplying 5.15 V on VBUS with a constant current limit up to 1.2 A.
