IN MODE TOL GND RST RST NMI VCC NC – – – – – – – – – Input Selects input pin characteristics Selects 5% or 10% VCC detect Ground Reset (Active High) Reset (Active Low, open drain) Non–Maskable Interrupt +5V Supply No Connections DESCRIPTION The DS1231 Power Monitor Chip uses a precise temperature-compensated reference circuit which provides an orderly shutdown and an automatic restart of a processor-based system.
A signal warning of an impending power failure is generated well before regulated DC voltages go out of specification by monitoring high voltage inputs to the power supply regulators.
If line isolation is required a UL-approved opto-isolator can be directly interfaced to the DS1231.
