... MC34164 § Operating temperature of -40°C to +85°C DESCRIPTION The DS1233M EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (V power-fail signal is generated which forces reset to the active (low) state. When V intolerance condition, the reset signal is kept in the active state for approximately 350 ms to allow the power supply and processor to stabilize ...

... OPERATION - POWER MONITOR The DS1233M provides the functions of detecting out-of-tolerance power supply conditions and warning a processor-based system of impending power failure. When V defined by the tolerance of the part selected, the RST signal is asserted. On power-up, RST is kept active for approximately 350 ms after the power supply has reached the selected tolerance. This allows the power supply and microprocessor to stabilize before RST is released ...
