POR and UVLO
To prevent ambiguous power-supply conditions from
corrupting the data in memory and causing erratic
behavior, a POR voltage detector monitors V
CC
and
clears the memory if V
CC
falls below 2.0V (typ). When
power is first applied and V
CC
rises above 2.0V (typ),
the logic blocks begin operating, although reads and
writes at V
CC
levels below 3V are not recommended. A
second V
CC
comparator, the ADC UVLO comparator
prevents the ADC from converting until there is suffi-
cient headroom (V
CC
= 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.

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.

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.

0
A 1 indicates the remote (external) junction temperature exceeds the external
OVERT
