Table 25. Alarm Status and Clear Alarm Status Register

Address

Default

Data Bits, MSB first

0x43

Alarm status

0x0000

This register is a read-only register providing information on the status of the alarm functions and

the comparator outputs.

Bit

Name

Function

LTMPALM

Latched temperature alarm bit; if low, this bit indicates that an alarm event has

occurred.

TMPALM

Unlatched alarm bit; if low, these bit indicates that an alarm event is still

present.

LOSALM

Latched open-sense alarm bit; if low, indicates that an alarm event has

occurred.

OSALM

Unlatched open-sense alarm bit; if low, indicates that an alarm event is still

present.

LDUTALM

Latched DUTGND Kelvin sense alarm; if low, indicates that an alarm event has

occurred.

DUTALM

Unlatched DUTGND Kelvin sense alarm; if low, indicates that an alarm event is still

present.

LCLALM

Latched clamp alarm; if low, indicates that an alarm event has occurred.

CLALM

Unlatched clamp alarm; if low, indicates that an alarm event is still present.

LGRDALM

Latched guard alarm; if low, indicates that an alarm event has occurred.

GRDALM

Unlatched guard alarm; if low, indicates that an alarm event is still present.

CPOL

Comparator output low condition as per the comparator output pin.

CPOH

Comparator output high condition as per the comparator output pin.

3:0

Unused

Must be zeros.

0x44

Alarm status

and clear alarm

0x0000

This register is a read-only register providing information on the status of the alarm functions and

the comparator outputs. Reading this register also automatically clears any latched alarm pins or bits.
