DESCRIPTION

The DS1233D 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 state. When V

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 DS1233D 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

power supply and microprocessor to stabilize before
