POR and UVLO
To prevent ambiguous power-supply conditions from
corrupting the data in memory and causing erratic
behavior, a POR voltage detector monitors VCC and
clears the memory if VCC falls below 2.0V (typ). When
power is first applied and VCC rises above 2.0V (typ),
the logic blocks begin operating, although reads and
writes at VCC levels below 3V are not recommended. A
second VCC comparator, the ADC UVLO comparator
prevents the ADC from converting until there is suffi-
cient headroom (VCC = 2.8V typ).
Power-Up Defaults
Power-up defaults include:
Interrupt latch is cleared.
ADC begins autoconverting at a 4Hz rate.
Command byte is set to 00h to facilitate quick local
temperature receive byte queries.
Local (internal) THIGH limit set to +85°C.
Local (internal) TLOW limit set to 0°C.
Remote (external) THIGH limit set to +85°C.
Remote (external) TLOW limit set to 0°C.
OVERT internal limit is set to +85°C; every external
limit is set to +110°C (MAX6648).
OVERT limits are set to +85°C (MAX6692).
Applications Information
Remote-Diode Selection
The MAX6648/MAX6692 can directly measure the die
temperature of CPUs and other ICs that have on-board
temperature-sensing diodes (see Typical Operating
Circuit), or they can measure the temperature of a dis-
crete diode-connected transistor.

7 (MSB)
BUSY
0
A/D is busy converting when 1.
6
LHIGH
0
Local (internal) high-temperature alarm has tripped when 1; cleared by POR or readout of the
status byte if the fault condition no longer exists.
5
LLOW
0
Local (internal) low-temperature alarm has tripped when 1; cleared by POR or readout of the
status byte if the fault condition no longer exists.
4
RHIGH
0
Remote (external) high-temperature alarm has tripped when 1; cleared by POR or readout of the
status byte if the fault condition no longer exists.
3
RLOW
0
Remote (external) low-temperature alarm has tripped when 1; cleared by POR or readout of the
status byte if the fault condition no longer exists.
2
FAULT
0
A 1 indicates DXN and DXP are either shorted or open; cleared by POR or readout of the status
byte if the fault condition no longer exists.
1
EOT
0
A 1 indicates the remote (external) junction temperature exceeds the external OVERT threshold.
0
IOT
0
A 1 indicates the local (internal) junction temperature exceeds the internal OVERT threshold.
