Description
General part information
BQ24298 Series
The bq24298 is a highly-integrated switch-mode battery charge management and system power path management device for 1 cell Li-Ion and Li-polymer battery in a wide range of smart phone and tablet applications. 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 3.9V – 6.2V USB input sources, including standard USB host port and USB charging port with 6.4V over-voltage protection. The device supports USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. To set the default input current limit, the bq24298 takes the result from the detection circuit in the system, such as USB PHY device. The device also supports USB On-the-Go operation by providing fast startup and supplying adjustable voltage 4.55 – 5.5V (default 5V) on the VBUS with an accurate current limit up to 1.5A.
