DESCRIPTION

The DS1833 EconoReset uses a precision temperature compensated reference and comparator circuit to

monitor the status of the power supply (V_CC). When an out-of-tolerance condition is detected, an internal

power fail signal is generated which forces reset to the active (high) state. When V_CCreturns to an in-

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_CCis detected as out-of-tolerance, as

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.
