DESCRIPTION

The DS1811 EconoReset uses a precision temperature 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 state. When VCC returns to an in-tolerance condition,

the reset signal is kept in the active state for approximately 150 ms to allow the power supply and

processor to stabilize.
