The TPS65820 has two dedicated internal controllers that execute the host interface and system sequencing
tasks: a sequencing controller and an interrupt controller.
The sequencing controller monitors internal and system parameters and defines the sequencing of the internal
power supplies during power up and power down / power fault events, and executes specific internal power
supply reset operations under external hardware control or host software commands.
The following parameters are monitored by the sequencing controller :
System power bus voltage (at SYS_IN pin), input supply voltage, battery pack voltage
TPS65820 thermal fault status
Integrated supply status
The interrupt controller monitors multiple system status parameters and signals to the host when one of the
monitored parameters toggled, as a result of a system status change. The interrupt controller inputs include all
the parameters monitored by the sequencing controller plus:
Charger status
Battery pack status
ADC status
Internal I2C registers enable masking of all the monitored parameters. Using those registers the host can select
which parameters trigger an interrupt or a power good fault. Power good faults trigger a change in the TPS65820
operating mode, as detailed in the next sections.
A simplified block diagram for the TPS65820 sections that interface to the external host is shown in Figure 27.
