MAX13036 datasheet(4/17 Pages) MAXIM

4 / 17 page

Note 1: All units are 100% production tested at TA = +125°C. Limits over the operating temperature range are guaranteed by cor-

relation to the +125°C tests.

Note 2: The total supply current is the sum of the current flowing into VL, BAT, and BATREF.

Note 3: VTH_C = (VTH_HIGH + VTH_LOW)/2.

Note 4: VTH_HYS = (VTH_HIGH - VTH_LOW).

Note 5: Wetting current rise/fall time is measured as the time from 10% to 90% of the maximum wetting current.

Note 6: Guaranteed by design.

(VL = +2.7V to +5.5V, BAT = +6V to +26V, SD = VL, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VL = +3.3V,

BAT = +14V, TA = +25°C) (Note 1)
