Figure 31. TPS65810 Charger and Power Path Section Simplified Block Diagram
The power path has three integrated power MOSFETs: the battery to system MOSFET (battery switch), the AC
input to system MOSFET (AC switch) and the USB input to system MOSFET (USB switch). Each of those power
MOSFETs can be operated either as an ON/OFF switch or as a linear pass element under distinct operating
conditions, as defined by the control circuits that set the power MOSFET gate voltage.
