AS6200 − Detailed Descriptions

Sleep Mode, Bit D8

The sleep mode is activated by setting the bit SM in the

configuration register to 1. This shuts the device down

immediately and reduces the power consumption to a

minimum value.

The serial interface is the only active circuitry in the sleep mode

in order to provide access to the digital registers.

After resetting the SM bit to 0, the device enters the continuous

conversion mode.

Sleep Mode Configuration

Interrupt Mode, Bit D9

The interrupt mode bit defines whether the device operates in

the temperature comparator mode or interrupt mode. This

defines the operation mode of the ALERT output as described

in the polarity bit section.

Figure 17:

Interrupt Mode Configuration

The comparator mode is characterized that if the temperature

value exceeds the THIGH value, the alert output is changed (e.g.

from high to low if the polarity bit is set to 0 and vice versa).

The alert output stays in that condition until the measured

temperature drops below the defined TLOW value.

The interrupt mode is characterized that it changes the alert

output as soon as the measured temperature crosses the THIGH

or TLOW value threshold.

The alert bit has the same setting as the alert output if the

device is set to comparator mode.
