DESCRIPTION
The DS1833 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 (high) state. When V
tolerance 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 DS1833 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.
