Description
General part information
BQ24292I Series
The bq24292i is highly-integrated switch-mode battery charge management and system power path management devices for single cell Li-Ion and Li-polymer battery in a wide range of smartphone, 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, the device detects the input source following the USB battery charging spec 1.2, and takes the results from detection circuit in the system, such as USB PHY device. The device is compliant with USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. Meanwhile, the device supports USB On-the-Go operation by providing fast startup and supplying 5V on the VBUS with a current limit up to 1.3A.
