SGM820 Precision Voltage Supervisor with Integrated Watchdog Timer GENERAL DESCRIPTION The SGM820 combines a precision voltage supervisor with a programmable watchdog timer. The SGM820 is suitable for monitoring common rail voltages of 1.8V, 2.5V, 3V, 3.3V and 5V. The SGM820 comparator achieves a high accuracy (-40℃ to +125℃) for the under-voltage threshold and also includes accurate hysteresis, making the device ideal for use with tight tolerance systems. The supervisor nRESET delay features a high accuracy, high-precision delay timing. The SGM820 includes a programmable watchdog timer for a wide variety of applications. The dedicated watchdog output (nWDO) enables increased resolution to help determine the nature of fault conditions.
