Power-down mode
Power dip of VCC < 8.6 V:
The soft-down sequence is started first.
Then the soft-start sequence is generated internally.
Power dip of VCC < 8.1 V or VCC shut-down:
This function is independent from the operating mode, so it works under any condition.
All driver outputs are immediately disabled
IC enters standby mode.
