DESCRIPTION

The DS1233 EconoReset monitors two vital conditions for a microprocessor: power supply and external

override. A precision temperature compensated reference and comparator circuit are used 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 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. The second function of the DS1233 is pushbutton reset control. The DS1233

debounces a pushbutton closure and will generate a 350 ms reset pulse upon release.

OPERATION - POWER MONITOR

The DS1233 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.
