... Push-pull active high output § Operating temperature -40°C to +85°C DESCRIPTION The DS1812 EconoReset uses a precision temperature reference and comparator circuit to monitor the status of the power supply (V signal is generated which forces reset to the active state. When V the reset signal is kept in the active state for approximately 150 ms to allow the power supply and processor to stabilize ...

... OPERATION - POWER MONITOR The DS1812 provides the function of detecting out-of-tolerance power supply conditions and warning a processor-based system of impending power failure. When V signal is asserted. On power-up, RST is kept active for approximately 150 ms after the power supply has reached the selected tolerance. This allows the power supply and microprocessor to stabilize before RST is released ...
