DS1231S-20+ - Maxim Integrated Function Overview

The DS1231S-20+ is a power monitor chip in 16 pin WSOIC package. This power monitor detects out of tolerance power supply conditions and warns a processor based system of impending power failure. It 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 IC.
Supply voltage range is 4.5V to 5.5V
Operating temperature range from 0°C to 70°C
Provides time for an orderly shutdown, active-high, push-pull / active-low, push-pull reset type
Prevents processor from destroying non-volatile memory during power transients
Automatically restarts processor after power is restored
Suitable for linear or switching power supplies
Adjusts to hold time of the power supply
Supplies necessary signals for processor interface
No external capacitors required, VCC trip point is 4.62V at (TOL=GND)
Replaces power-up reset circuitry
