ELECTRICAL CHARACTERISTICS (continued)
(VIN = +1.7V to +5.5V, RSETI = 94.2k
Ω, CIN = COUT = 1F, and TA = TJ = -40°C to +125°C, unless otherwise noted. Typical values
are at VIN = +3.3V, TA = +25°C.) (Note 2)
Note 2: All devices are 100% tested at 125°C. Electrical limits across the full temperature range are guaranteed by design and correlation.
Note 3: Blanking time and retry time are generated by the same oscillator. Therefore, the ratio of
is a constant value of 32.
See Figures 2 and 3.
