This IC has protective functions which are

Under Voltage Lock Out (UVLO) and Over

Voltage Protection (OVP).

The active level of UVLO is under 2.9V

(typical) at VCC and the return level is over

3.1V (typical). If UVLO is active, Both of

OUT1 and OUT2 are under sleep mode.

The active level of OVP is over 19.8V

(typical) at VCC and the return level is under

17.8V (typical). If OVP is active, high side of

OUT1 and OUT2 is into sleep but low side

keeps on operating according to input

signals.
