Shutdown Mode
To reduce current consumption and save power, the device features a Shutdown Mode that
disables all internal device circuitry except for the serial interface and POR circuits. While in the
Shutdown Mode, the internal temperature sensor is not active, so no temperature measurements
will be made.
Entering and exiting the Shutdown Mode is controlled by the SD bit in the
Configuration Register.
Entering the Shutdown Mode can affect the ALERT pin depending on the Alarm Thermostat
Mode. If the device is configured to operate in the Interrupt Mode, then the ALERT pin will go
inactive when the device enters the Shutdown Mode. However, the ALERT pin will not change
states if the device is operating in the Comparator Mode.
The fault count information will not change when the device enters or exits the Shutdown Mode.
Therefore, the number of previous temperature faults recorded by the internal fault counter will be
retained unless the device is power-cycled or reset.
When exiting the Shutdown Mode, the
ALERT pin will go active if operating in Interrupt Mode, a valid fault condition exists, and the
THIGH and TLOW event cycles are maintained (i.e. THIGH event before entering Shutdown Mode
followed by a TLOW event when exiting Shutdown Mode).
The device can be powered-down while in the Shutdown Mode so that it will remain in the
Shutdown Mode after the subsequent power-up operation. This is accomplished by setting the
NVSD bit in the Nonvolatile Configuration Register to the logic “1” state prior to power-down.
Upon power-up or reset, the device will first copy the contents of the nonvolatile data registers
into the volatile data registers, after which the device will perform a single temperature
measurement and store the result in the Temperature Register. After this process is complete,
the device will re-enter the Shutdown Mode.
5.3.1
One-Shot Mode
The AT30TS750 features a One-Shot temperature mode that allows the device to perform a
single temperature measurement while in the Shutdown Mode. By keeping the device in the
Shutdown Mode and utilizing the One-Shot Mode, the AT30TS750 can remain in a lower power
