2.3.3 BQ25616

The BQ25616 (and BQ25616J) is a highly integrated 3-A switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer batteries. The device is highly integrated with input reverse-blocking field-effect transistor (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 run time during the discharging phase.

The device features fast charging with high-input voltage support for a wide range of applications including speakers, industrial, and medical portable devices. The input voltage and current regulation deliver maximum charging power to the battery. The design also integrates the bootstrap diode for the high-side gate drive for simplified system design. The hardware setting and status report provides easy configuration to set up the charging design.

The device supports a wide range of input sources, including standard USB host port, USB charging port, USB compliant high voltage adapter and wireless power. The device is compliant with USB 2.0 and USB 3.0 power spec with input current and voltage regulation. The device sets default input current limit based on the built-in USB detection through D+ and D– pins. When the device built-in USB interface identifies the input adapter is unknown, the device’s input current limit is determined by the ILIM pin setting resistor value.
