UVTH Input Falling

Threshold vs. Temperature.

Data taken with the minimum following conditions:

IPOS = 5 mA

(Enables VPOS at its self-regulating voltage)

VREFIN = 2.5V, ISET = 10 µA

Use PWRGOOD pin as indicator

Note 1:

VOVTH < VVREFIN

VSENSE = VVNEG

VVFB = VVNEG

VDRAINTH = VVNEG

VOVO = VVNEG

VCL = VVREFIN

VENABLE = 5V (open)

VRESTART = VVNEG (open)
