7.4.1 Device Functional Modes

During typical operation, the TPS1HTC100-Q1 can operate in a number of states that are described below and shown as a state diagram in Figure 7-13.

OFF - Off state occurs when the device is not powered.

STANDBY - Standby state is a low-power mode used to reduce power consumption to the lowest level. Diagnostic capabilities are not available in standby mode.

STANDBY DELAY - The standby delay state is entered when EN and DIAG_EN are low. After tSTBY, if the EN and DIAG_EN pins are still low, the device will go to standby state.

DIAGNOSTIC - Diagnostic state may be used to perform diagnostics while the switch is disabled.

ACTIVE - In active state, the switch is enabled. The diagnostic functions may be turned on or off during active state.
