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.
" Local (internal) T
HIGH
limit set to +85癈.
" Local (internal) T
LOW
limit set to 0癈.
" Remote (external) T
HIGH
limit set to +85癈.
" Remote (external) T
LOW
limit set to 0癈.
" OVERT internal limit is set to +85癈; every external
limit is set to +110癈 (MAX6648).
" OVERT limits are set to +85癈 (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.
Effect of Ideality Factor
The accuracy of the remote temperature measurements
depends on the ideality factor (n) of the remote diode
BIT
NAME

FUNCTION
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.
