conversion results until they have been read. If the
most significant bits have not been read within an
SMBus timeout period (nominally 37ms), normal updat-
ing continues. Table 1 shows the main temperature
register (high byte) data format, and Table 2 shows the
extended resolution register (low byte) data format.
Diode Fault Detection
If a channel’s input DXP_ and DXN_ are left open or
shorted together, the MAX6699 detects a diode fault. A
diode fault, whether a short or an open circuit, does not
cause either
ALERT
or
OVERT
to assert. A bit in the sta-
tus register for the corresponding channel is set to 1, and
the temperature data for the channel is stored as all 1s. It
takes approximately 4ms for the MAX6699 to detect a
diode fault. Once a diode fault is detected, the MAX6699
jumps onto the next channel in the conversion sequence.

Slave Address: equiva-
lent to chip-select line of
a 3-wire interface
Command Byte: selects to
which register you are writing
Data Byte: data goes into the register
set by the command byte (to set
thresholds, configuration masks, and
sampling rate)
Slave Address: equiva-
lent to chip-select line
Command Byte: selects
from which register you
are reading
Slave Address: repeated
due to change in data-
flow direction
Data Byte: reads from
the register set by the
command byte
Command Byte: sends com-
mand with no data, usually
used for one-shot command
Data Byte: reads data from
the register commanded
by the last read byte or
write byte transmission;
also used for SMBus alert
