The MAX6696’s registers are reset to their power-on
values if RESET is driven high. When reset occurs, all
registers go to their default values, and the SMBus
address pins are sampled.

A/D is busy converting when 1.
When 1, internal high-temperature ALERT has tripped, cleared by POR or by reading this status
register. If the fault condition still exists, this bit is set again after the next conversion.
When 1, internal low-temperature ALERT has tripped, cleared by POR or by reading this status
register. If the fault condition still exists, this bit is set again after the next conversion.
A 1 indicates external junction 1 high-temperature ALERT has tripped, cleared by POR or by
reading this status register. If the fault condition still exists, this bit is set again after the next
conversion.

A 1 indicates external diode 1 is open, cleared by POR or by reading this status register. If the
fault condition still exists, this bit is set again after the next conversion.
A 1 indicates external junction 1 temperature exceeds the OT1 threshold, cleared by reading this
register.
A 1 indicates internal junction temperature exceeds the internal OT1 threshold, cleared by
reading this register.
A 1 indicates internal junction temperature exceeds the internal OT2 threshold, cleared by
reading this register.
A 1 indicates external junction temperature 2 exceeds the external OT2 threshold, cleared by
reading this register.
A 1 indicates external junction temperature 1 exceeds the OT2 threshold, cleared by reading this
register.
A 1 indicates external junction 2 high-temperature ALERT has tripped; cleared by POR or readout
of the status register. If the fault condition still exists, this bit is set again after the next conversion.
A 1 indicates external junction 2 low-temperature ALERT has tripped; cleared by POR or readout
of the status register. If the fault condition still exists, this bit is set again after the next conversion.
A 1 indicates external diode 2 open; cleared by POR or readout of the status register. If the fault
condition still exists, this bit is set again after the next conversion.
A 1 indicates external junction 2 temperature exceeds the OT1 threshold, cleared by reading this
register.

The conversion-rate control register (Table 9) programs
the time interval between conversions in free-running
autonomous mode (RUN/STOP = 0). This variable rate
control can be used to reduce the supply current in
portable-equipment applications. The conversion rate
