AS6200 − Detailed Descriptions

High- and Low-Limit Registers

If the comparator mode is configured (IM=0), the ALERT output

becomes active if the temperature equals or exceeds the

defined value in register THIGH for the configured number of

consecutive faults (N). This configuration is defined by the field

CF in the configuration register. The ALERT output remains

assigned until the converted temperature value equals or falls

below the defined value in register TLOW for the same number

of consecutive fault cycles.

If the interrupt mode is configured (IM=1), the ALERT output

becomes active if the temperature equals or exceeds the

defined value in register THIGH for the configured number of

consecutive fault cycles. It remains active until a read operation

is executed on any register. The ALERT output is also cleared if

the device is set into sleep mode by setting bit SM in the

configuration register.

Once the ALERT output is cleared, it is activated again only if

the temperature value falls below the configured value in

taken place.

This sequence is repeated unless the device is set into the

comparator mode or reset by the General Call Reset command.

This reset command clears the interrupt mode bit and

consequently puts the device into the comparator mode.

The sequential behavior is summarized in the following figure.
