SLVS606C – SEPTEMBER 2005 – REVISED FEBRUARY 2007
The TPS65800 has an integrated charger with power path integrated MOSFETs. This topology, shown in the
simplified block diagram below, enables using an external input power to run the system and charge the battery
simultaneously. The power path has dual inputs that can be used to select either an external AC_DC adapter
(AC pin) or an USB port power (USB pin) to power the end equipment main power rail (OUT pin, also referred to
as the system power bus) and charge the battery pack (connected to BAT pin).
