The BQ24192IRGET is a highly-integrated switch-mode Battery Charge and System Power Path Management Device for single cell Li-ion and Li-polymer battery in a wide range of tablet and other portable devices. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging 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 a wide range of input sources, including standard USB host port, USB charging port and high power DC adapter. To set the default input current limit. It takes the results from detection circuit in the system, such as USB PHY device. It compliant with the USB 2.0 and USB 3.0 power specifications with input current and voltage regulation and meets USB On-the-Go operation power rating specification by supplying 5V on the VBUS with a current limit up to 1.3A.
