Overview

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.

Features
  • Support up to 3A charging current
  • Highly integrated solution with the highest efficiency
  • Support Shipping Mode and System Reset
  • I2C Forced BATFET Off with Delay (9 s Typ)
  • Both host control and autonomous charging when the host is not available
  • Integrated low Rdson battery FET for long battery run time

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
