MAX6657/MAX6658/MAX6659
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 VCC, 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.
