Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(VIN1–VIN4 or VCC = 2.7V to 5.8V, WDI = GND, TH0–TH4 = MARGIN = MR = DBP, TA = -40°C to +85°C, unless otherwise noted.
Typical values are at TA = +25°C.) (Notes 1, 2)

CONDITIONS
Voltage on either one of IN1–IN4 or VCC to
guarantee the part is fully operational
VIN1 = 5.8V, IN2–IN6 = GND, no load
IN1–IN6, VIN _ falling
TA = +25oC to +85oC
TA = -40oC to +85oC
For VIN_ < highest VIN1–IN4 and VIN_ < VCC
(not ADJ), thresholds are not set as
adjustable
IN5, IN6
IN1–IN4 set as adjustable thresholds
VCC ≥ 2.5V
IN_ falling/rising, 100mV overdrive
VSRT = VCC
CSRT = 47nF
VSRT = VGND
VSRT ≥ VSRT-DEF, selects reset default
VSRT-ADJ (Note 4)
