3 Different Alert Output Types

The three main types of alerts are overtemperature, undertemperature, and window monitoring. There are different ways in which the signal can be displayed but still contain the same functionality. For digital sensors, the settings must be adjusted within the I2C registers to change the desired output. The different output options are highlighted as follows:

  • Polarity
  • Comparator/ Interrupt Mode
  • Fault and Masking Conditions
  • Push-Pull and Open Drain
  • Digital Output
