BQ24193RGET

The BQ24193RGET is a single cell USB/Adaptor Charger with narrow VDC power path. 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. It takes the result from detection circuit in the system, such as USB PHY device. Complaints with USB 2.0 and USB 3.0 power spec with input current and voltage regulation. Meanwhile, meets USB On-the-Go operation power rating specification by supplying 5V on VBUS with current limit up to 1.3A. The power path management regulates the system slightly above battery voltage but does not drop below 3.5V minimum system voltage (programmable).
