The LTC2962 series of configurable power supply monitorscan supervise systems with up to four supply voltages.One of 16 preset or adjustable voltage monitorthresholds per channel can be selected using external 1%resistors connected to the programming (PG) inputs. Thepreset voltage thresholds are accurate to ±0.5% over temperature.Positive (+ADJ) and negative (−ADJ) adjustableinputs with a 0.5V threshold allow undervoltage, negativevoltage and overvoltage monitoring.
The watchdog (LTC2963 only) and reset timeout periodsare adjustable using external capacitors. Accurate voltagethresholds and comparator glitch immunity ensurereliable reset operation without false triggering. The RSToutput is guaranteed to be in the correct state for VCCinput voltage down to 1V.
The flexibility of the LTC2962 family provides the abilityto monitor a wide variety of power supply combinations,including multiple supplies of the same voltage, with ±0.5% accuracy.
