MAX6884/MAX6885
EEPROM-Programmable, Hex
Power-Supply Supervisory Circuits
_______________________________________________________________________________________ 5
Note 1: 100% production tested at T
A
= +25°C and T
A
= +85°C. Specifications at T
A
= -40°C are guaranteed by design.
Note 2: Device may be supplied from IN1–IN4 or V
CC
.
Note 3: The internal supply voltage, measured at V
CC
, equals the maximum of IN1–IN4.
Note 4: V
IN_
> 0.3 x ADC range.
Note 5: Does not include the inaccuracy of the 1.25V input reference voltage (MAX6884 only).
Note 6: DNL is implicitly guaranteed by design in a
Σ∆ converter.
Note 7: C
BUS
= total capacitance of one bus line in picofarads. Rise and fall times are measured between 0.1 x V
BUS
and 0.9 x
V
BUS
.
Note 8: Input filters on SDA, SCL, and A0 suppress noise spikes <50ns.
Note 9: An additional cycle is required when writing to configuration memory for the first time.
