Description
General part information
BQ24297 Series
The BQ24296/BQ24297 are highly-integrated switch-mode battery charge management and system power path management devices for 1 cell Li-Ion and Li-polymer batteries in a wide range of smart phone and tablet applications.
Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charge time and extends battery life during discharging phase. The I 2C serial interface with charging and system settings makes the device a truly flexible solution.
The device supports 3.9-V to 6.2-V USB input sources, including standard USB host port and USB charging port with 6.4-V 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 BQ24297 detects the input source through D+/D- detection following the USB battery charging spec 1.2. In addition, the BQ24297 detects non-standard 2-A/1-A adapters. The device also supports USB On-the-Go operation by providing fast startup and supplying adjustable voltage 4.55-V to 5.5-V (default 5 V) on the VBUS with an accurate current limit up to 1.5 A.
