MLX75030 Universal ActiveLight Sensor Interface
Datasheet
The Critical Error Flag will also be set high when a falling edge on the WT pin will be detected while the device is in Sleep
Mode.
Following nodes are monitored:
- TIA output: when the output is clipped (either high or low), the Critical Error Flag will be set high
- Difference between DAC output and shunt-feedback
- An internal reference voltage
- Output of the common mode SC-amplifiers of the Ambient Light/Temperature Channels
- Frequency on RCO output
In case the Critical Error Flag was set high, the 'Err' register indicates which node voltages got out of their normal operating
range. More info about the 'Err' register can be found in Section 7.4.7.
The Critical Error Flag remains high as long as the 'Err' register is not cleared. Once the 'Err' register is cleared, the Critical
Error Flag will be cleared as well.
Note: after POR, or after wake-up from Sleep/Standby, some bits in the 'Err' register might be set. As such the Critical Error
Flag might be set as well.
