DESCRIPTION
The DS1833 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 (high) state. When VCC returns to an intolerance
condition, the reset signal is kept in the active state for approximately 350 ms to allow the
power supply and processor to stabilize.
