The SGM820 is a family of high-accuracy supervisory circuits with programmable watchdog timer. It provides various under-voltage threshold voltage options for 1.8V, 2.5V, 3V, 3.3V and 5V system rail voltage monitoring. Besides, the nRESET delay of the SGM820 has a high-precision delay timing. And combined with its accurate voltage monitoring hysteresis, the SGM820 is very suitable for strict tolerance systems.
The SGM820 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.
The SGM820 is available in Green TDFN-3×3-8L and TDFN-2×2-8L packages. It operates over an ambient temperature range of -40℃ to +125℃.
