register. If extended resolution is desired, the extended
resolution register should be read first. This prevents
the most significant bits from being overwritten by new
conversion results until they have been read. If the most
significant bits have not been read within an SMBus
timeout period (nominally 37ms), normal updating con-
tinues. Table 1 shows the main temperature register
(high-byte) data format, and Table 2 shows the extend-
ed resolution register (low-byte) data format.
Diode Fault Detection
If a channels input DXP_ and DXN_ are left open, the
MAX6636 detects a diode fault. An open diode fault does
not cause either ALERT or OVERT to assert. A bit in the
status 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 MAX6636 to
detect a diode fault. Once a diode fault is detected, the
MAX6636 goes to the next channel in the conversion
sequence. Depending on operating conditions, a shorted
diode may or may not cause ALERT or OVERT to assert,
so if a channel will not be used, its DXN and DXP inputs
should be left unconnected.
