6.2.7

Consecutive Faults

A fault condition persists if the measured temperature either exceeds the configured value in register

THIGH or falls below the defined value in register TLOW. As a result, the ALERT pin indicates the

fault condition if a defined number of consecutive temperature readings meets this fault condition. The

number of consecutive faults are defined with two bits (12 and 11) and prevent a false alert if

environmental temperature noise is present. The register configuration is shown in the following table.

Single Shot Conversion

The device features a single shot measurement mode if the device is in sleep mode (SM=1). By

setting the “Single Shot-bit” to 1, a single temperature conversion is started and the SS-bit can be read

as 1 during the active conversion operation. Once the conversion is completed, the device enters the

sleep mode again and the SS-bit is set to 0. The single shot conversion allows very low power

consumption since a temperature conversion is executed on demand only. This allows a user defined

timing of the temperature conversions to be executed and is used if the consecutive operation mode is

not required.

As the device exhibits a very short conversion time, the effective conversion rate can be increased by

setting the single shot bit repetitively after a conversion has finished. However, it has to be ensured

that the additional power is limited, otherwise self-heating effects have to be considered.
