NOTES
NOTES
1.
All voltages are referenced to V
SS
.
2.
Specified with no resistive load on CC, DC, or CP.
3.
Contact the factory for different voltage trip points and delay periods.
4.
Typical load capacitance on CC, DC is 1000pF CP (charge pump reservoir cap) = 0.1 F. DC load
total on CC, DC, CP > 10M .
5.

6.
Maximum high-to-low fall time is 5 s.
7.
Internal 10V clamp on DC pin limits DC output logic low when PLS > 10V
