APPLICATION INFORMATIONS
The timing diagram of VDD and VOUT is shown in below:
CMOS Type
VDET
VDD
VHYS
The guaranteed minimun operation voltage is 1.5V.
As the supply voltage(VDD) is reduced below 1.5V,
the performance degrades, N-ch or P-ch driving capacity degrades, and the supply current decreases.
AIC1680 isn’t functioning when VDD down to 0.8V.
