Maxim Integrated Voltage Supervisor 8-Pin SOIC, DS1233MS-5+

The DS1233M EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power fail signal is generated, which forces reset to the active (low) state. When VCC 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.
