Power Switch Interface
The power switch interface of the PCI6x20 device is a 3-pin serial interface. This 3-pin interface is implemented such
that the PCI6x20 device can connect to both the TPS2226 and TPS2228 power switches. Bit 10 (12V_SW_SEL) in
the general control register (PCI offset 86h, see Section 4.31) selects the power switch that is implemented. The
PCI6x20 device defaults to use the control logic for the TPS2228 power switch. See Table 3
–
2 through Table 3
–

for the power switch control logic.
