5Vエコノリセット

The DS1233D EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (V_CC). When an out-of-tolerance condition is detected, an internal power-fail signal is generated, which forces reset to the active state. When V_CC returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 350ms to allow the power supply and processor to stabilize.
