POWER MANAGEMENT
Notes:
(1) V
PWR
= input voltage to pass device drains (or sources depending upon orientation of FETs).
(2) If V
TH(UV)
is exceeded for longer than 50祍 (nom.) the protection circuitry will shut down that output.
(3) During startup only, V
TH(PGD)
is -6% (typ.), then switches to -12% (typ.).
