VCC < 8.1 V

VCC

a soft-down sequency followed by a

soft start sequence is generated

internally.

(1) See Fig.20.

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.
