The SGM820xQ is a family of high-accuracy supervisory circuits with programmable watchdog timer. It provides three under-voltage threshold voltage options of 1.674V, 2.325V and 3.069V (TYP) for 1.8V, 2.5V and 3.3V system rail voltage monitoring. Besides, the nRESET delay of the SGM820xQ has a high-precision delay timing. And combined with its accurate voltage monitoring hysteresis, the SGM820xQ is very suitable for strict tolerance systems. 

The SGM820xQ has a programmable watchdog timer. Users can program the timeouts through an external capacitor or the default factory settings. In addition, users can disable the watchdog through logic pins to prevent accidental timeouts during development. 

This device is AEC-Q100 qualified (Automotive Electronics Council Standard Q100 Grade 1) and the use of this device is suitable for automotive applications. 

The SGM820xQ is available in Green TDFN-3×3-8GL and TDFN-2×2-8DL packages. It operates over an ambient temperature range of -40℃ to +125℃.
