Unpowered Mode
If you connect battery voltage to the application circuit, the voltage at the VS pin increases
according to the block capacitor (see
Figure 3-7 on page
17). After VS is higher than the VS
undervoltage threshold VS
, the IC mode changes from Unpowered Mode to Fail-safe Mode.

The VCC output voltage reaches its nominal value after t
. This time, t
, depends on the
