V
DQ
– V
THM
. The THM pin must not be driven to a higher voltage than the DQ pin.
The application thermistor cannot exceed the R
DQ-THM
resistance range over operating temperature. If thermistor mode is not used in the application, it is
recommended that a 50K
resistor be connected between DQ and THM pins instead.
Maximum leakage of DQ pin while in thermistor mode.
When performing a Lock Secret (0x6A), Set Overdrive (0x8B) or Clear Overdrive (0x8D) operation, there will be an increased operating current of I
PGM-
during the time period from when the command is issued until the next 1-Wire bus reset. I
PGM-IDLE
current will be present before and after the program
pulse.
See Figure 11 for definitionof t
PPR
, t
PPW
, and t
PPF.
All voltages referenced to VSS.
V
DQ
must be at least 3.0V when the 1-Wire bus is idle.
Drive strength at time=0 after Activate Thermistor command is sent to the DS2703.
Does not include capacitance referred from VB pin on initial power up.
EEPROM data read retention is four years at +50°C
Time from msb of Activate Thermistor command until THM pin is driven low internally.
Time from msb of Compute Next Secret or Compute MAC command.
Time after initial power up before the DS2703 will respond to communication. T
STRT
specifications are valid only if the capacitor on VB (C
VB
) is 0.22
