8.4 Device Functional Modes

Table 1 describes all of the functional modes for the TPD8S300A. The "X" in the below table are "do not care" conditions, meaning any value can be present within the absolute maximum ratings of the datasheet and maintain that functional mode. Also note the D1, D2, D3, and D4 pins are not listed, because these pins have IEC ESD protection diodes that are always present, regardless of whether the device is powered and regardless of the conditions on any of the other pins.

Table 1. Device Mode Table

Device Mode Table Inputs Outputs
MODE VPWR C_CCx C_SBUx RPD_Gx TJ FLT CC FETs SBU FETs
Normal Operating Conditions Unpowered, no dead battery support <UVLO X X Grounded X High-Z OFF OFF
Unpowered, dead battery support <UVLO X X Shorted to C_CCx X High-Z OFF OFF
Powered on >UVLO <OVP <OVP X, forced OFF <TSD High-Z ON ON
Fault Conditions Thermal shutdown >UVLO X X X, forced OFF >TSD Low (Fault Asserted) OFF OFF
CC over voltage condition >UVLO >OVP X X, forced OFF <TSD Low (Fault Asserted) OFF OFF
SBU over voltage condition >UVLO X >OVP X, forced OFF <TSD Low (Fault Asserted) OFF OFF
IEC ESD generated over voltage condition(1) >UVLO X X RD ON if RPD_Gx is shorted to C_CCx <TSD Low (Fault Asserted) OFF OFF
(1) This row describes the state of the device while still in OVP after the IEC ESD strike which put the device into OVP is over, and the voltages on the C_CCx and C_SBUx pins have returned to their normal voltage levels.
