GENERAL DEscriptION

The SGM820 is a high-accuracy supervisory circuit with programmable watchdog timer, which can realize the under-voltage threshold accuracy of less than 1% from -40 to +125. It provides ten reset threshold voltage options for 1.8V, 2.5V, 3V, 3.3V and 5V voltage monitoring.

The nRESET delay of the SGM820 has a high-precision delay timing. Due to its accurate hysteresis, the SGM820 is very suitable for using with 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.
