1. Initiate a one-shot conversion using Command
Byte 0Fh. When this conversion is complete, read
the contents of the Temperature Data registers.
2) If the MAX6657/MAX6658/MAX6659 are in run mode,
read the Status register. If a conversion is in
progress, the BUSY bit is set to 1. Wait for the con-
version to complete as indicated by the BUSY bit
being set to 0, then read the Temperature Data reg-
isters. Note that the power-on reset sets the conver-
sion rate to 16Hz, so no extended data is valid
without reducing the conversion rate to 4Hz or less.
Diode Fault Alarm
There is a continuity fault detector at DXP that detects
an open circuit between DXP and DXN, or a DXP short
to V
CC
, GND, or DXN. If an open or short circuit exists,
the external temperature register is loaded with 1000
0000. Additionally, if the fault is an open circuit, bit 2
(OPEN) of the status byte is set to 1 and the ALERT con-
dition is activated at the end of the conversion.
Immediately after POR, the Status register indicates that
no fault is present until the end of the first conversion.
