7-Channel Precision Temperature Monitor
with Beta Compensation
10 ______________________________________________________________________________________
Diode Fault Detection
If a channels input DXP_ and DXN_ are left open, the
MAX6693 detects a diode fault. An open diode fault 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 (FFh). It
takes approximately 4ms for the MAX6693 to detect a diode
fault. Once a diode fault is detected, the MAX6693 goes to
the next channel in the conversion sequence.
Alarm Threshold Registers
There are 11 alarm threshold registers that store over-tem-
perature ALERT and OVERT threshold values. Seven of
these registers are dedicated to storing one local alert tem-
perature threshold limit and six remote alert temperature
threshold limits (see the ALERT Interrupt Mode section).
The remaining four registers are dedicated to remote chan-
nels 1, 4, 5, and 6 to store overtemperature threshold limits
(see the OVERT Overtemperature Alarms section). Access
to these registers is provided through the SMBus interface.
ALERT Interrupt Mode
An ALERT interrupt occurs when the internal or external
temperature reading exceeds a high-temperature limit
(user programmable). The ALERT interrupt output signal
can be cleared by reading the status register(s) associ-
ated with the fault(s) or by successfully responding to an
alert response address transmission by the master. In
both cases, the alert is cleared but is reasserted at the
end of the next conversion if the fault condition still
exists. The interrupt does not halt automatic conversions.
The ALERT output is open-drain so that multiple devices
can share a common interrupt line. All ALERT interrupts
can be masked using the configuration 2 register. The
POR state of these registers is shown in Table 3.
