SOIC-8 IC POWER MONITOR DS1231-35
SOIC8 IC POWER MONITOR DS1231-35 - NOS
With precise, temperature-compensated comparators, the DS1231 Power Monitor Chip monitors input power and a 5V system power supply. If unsafe voltages are detected, a nonmaskable interrupt sends a warning signal to the processor in advance of power failure. Processing is unconditionally halted when power falls below a user-selectable 5% or 10% threshold level, with time to shutdown proportional to the available hold-up time of the power supply. Upon return of power, the DS1231 maintains reset until power conditions stabilize.
Monitors input and power supply and warns of impending failure
Initiates and holds processor reset until levels are unsafe
Tolerance threshold levels can be set for 5% or 10%
Automatically restarts processor on power-up
Pauses restart until system stabilizes
Active-low NMI Hysteresis (350mV = "-35")
