LTC2962 Series

The LTC2962 series of configurable power supply monitors can supervise systems with up to four supply voltages. One of 16 preset or adjustable voltage monitor thresholds per channel can be selected using external 1% resistors connected to the programming (PG) inputs. The preset voltage thresholds are accurate to ±0.5% over temperature. Positive (+ADJ) and negative (−ADJ) adjustable inputs with a 0.5V threshold allow undervoltage, negative voltage and overvoltage monitoring.The watchdog (LTC2963 only) and reset timeout periods are adjustable using external capacitors. Accurate voltage thresholds and comparator glitch immunity ensure reliable reset operation without false triggering. TheRSToutput is guaranteed to be in the correct state for VCCinput voltage down to 1V.The flexibility of the LTC2962 family provides the ability to monitor a wide variety of power supply combinations, including multiple supplies of the same voltage, with ±0.5% accuracy.APPLICATIONSHigh Reliability SystemsNetwork, Telecom and Server SystemsAutomotive Control Systems
