The BQ24296RGET is a single cell USB Charger with narrow VDC power path management and adjustable voltage USB. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charge time and extends battery life during discharging phase. The I²C serial interface with charging and system settings makes the device a truly flexible solution. The device supports 3.9 to 6.2V USB input sources, including standard USB host port and USB charging port with 6.4V over-voltage protection. The device is compliant with USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. To set the default input current limit, the bq24296 takes the result from the detection circuit in the system, such as USB PHY device and the bq24296 detects the input source through D+/D- detection.
