ELECTRICAL CHARACTERISTICS (continued)
(Typical Operating Circuit, VIN = 3.7V, CBATT = CIN1 = CIN2 = 2.2FF, CREFBP = 0.1FF, TA = -40NC to +85NC, unless otherwise noted.
Typical values are at TA = +25NC.) (Notes 3, 4)

Note 3: VIN1, VIN2, and VBATT are connected together and single input is referred to as VIN.
Note 4: All units are 100% production tested at TA = +25NC. Limits over the operating temperature range are guaranteed by
design.
Note 5: When the input voltage is greater than 2.85V (typ), the UVLO comparator trips, and the threshold is reduced to 2.35V
(typ). This allows the system to start normally even if the input voltage decays to 2.35V.
Note 6: Not production tested; guaranteed by design.
Note 7: DRON(MAX) = |RON(CH1) - RON(CH2)|.
Note 8: Flatness is defined as the difference between the maximum and minimum value of on-resistance, as measured over
specified analog signal ranges.
Note 9: Between any two switches.
