DS1233DZ-5+ Voltage Supervisor Type, Maxim Integrated Voltage Supervisor 3 + Tab-Pin SOT-223, DS1233DZ-5+

The DS1233D 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 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.
