9 Application and Implementation
NOTE
information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application information
A typical application consists of the device configured as an I²C controlled power path management device and a
single cell battery charger for Li-Ion and Li-polymer batteries used in a wide range of smart phones and other
portable devices. It integrates an input reverse-block FET (RBFET, Q1), high-side switching FET (HSFET, Q2),
low-side switching FET (LSFET, Q3), and battery FET (BATFET Q4) between the system and battery. The
device also integrates a bootstrap diode for the high-side gate drive.
