1°C Temperature Sensor with Beta Compensation
Datasheet
Unlike the ALERT pin, the THERM pin cannot be masked. Additionally, the THERM pin will be released
once the temperature drops below the corresponding threshold minus the THERM Hysteresis.

The External Diode Fault Register indicates which of the external diodes caused the FAULT bit in the
Status Register to be set. This register is cleared when it is read.
Bit 3 - E3FLT - This bit is set if the External Diode 3 channel reported a diode fault.
Bit 2 - E2FLT - This bit is set if the External Diode 2 channel reported a diode fault.
Bit 1 - E1FLT - This bit is set if the External Diode 1 channel reported a diode fault.

MASK MASK
The Channel Mask Register controls individual channel masking. When a channel is masked, the
ALERT pin will not be asserted when the masked channel reads a diode fault or out of limit error. The
channel mask does not mask the THERM pin.
Bit 3 - E3MASK - Masks the ALERT pin from asserting when the External Diode 3 channel is out of
limit or reports a diode fault.
‘0’ (default) - The External Diode 3 channel will cause the ALERT pin to be asserted if it is out of
limit or reports a diode fault.
‘1’ - The External Diode 3 channel will not cause the ALERT pin to be asserted if it is out of limit
or reports a diode fault.
Bit 2 - E2MASK - Masks the ALERT pin from asserting when the External Diode 2 channel is out of
limit or reports a diode fault.
‘0’ (default) - The External Diode 2 channel will cause the ALERT pin to be asserted if it is out of
limit or reports a diode fault.
‘1’ - The External Diode 2 channel will not cause the ALERT pin to be asserted if it is out of limit
or reports a diode fault.
Bit 1 - E1MASK - Masks the ALERT pin from asserting when the External Diode 1 channel is out of
limit or reports a diode fault.
‘0’ (default) - The External Diode 1 channel will cause the ALERT pin to be asserted if it is out of
limit or reports a diode fault.
‘1’ - The External Diode 1 channel will not cause the ALERT pin to be asserted if it is out of limit
or reports a diode fault.
