MAX31826
1-Wire Digital Temperature Sensor
with 1Kb Lockable EEPROM
Note 1: Limits are 100% production tested at T
A
= +25癈 and/or T
A
= +85癈. Limits over the operating temperature range and
relevant supply voltage range are guaranteed by design and characterization. Typical values are not guaranteed.
Note 2: All voltages are referenced to ground.
Note 3: The pullup supply voltage specification assumes that the pullup device is ideal, and therefore the high level of the pullup
is equal to V
PU
. To meet the devices V
IH
specification, the actual supply rail for the strong pullup transistor must include
margin for the voltage drop across the transistor when it is turned on; thus: V
PU_ACTUAL
= V
PU_IDEAL
+ V
TRANSISTOR
.
Note 4: Guaranteed by design. These limits represent a three sigma distribution.
Note 5: To guarantee a presence pulse under low-voltage parasite-power conditions, V
ILMAX
might need to be reduced to as low
as 0.5V.
Note 6: Logic-high voltages are specified at a 1mA source current.
Note 7: Standby current specified up to T
A
= +70NC. Standby current typically is 3FA at T
A
= +125NC.
Note 8: To minimize I
DDS
, DQ should be within the following ranges: V
GND
P V
DQ
P V
GND
+ 0.3V or V
DD
- 0.3V P V
DQ
P V
DD
.
Note 9: Active current refers to supply current during active temperature conversions or EEPROM writes.
Note 10: DQ line is high (high-impedance state).
Note 11: See the 1-Wire Timing Diagrams.
Note 12: Under parasite power, if t
RSTL
> 960Fs, a power-on reset (POR) can occur.
