  advertisement Versatile Voltage Monitors Simplify Detection of Overvoltage
  and Undervoltage Faults – Design Note 408
  Scott Jackson Introduction
  Many modern electronic systems have strict power supply
  operating ranges—requiring accurate monitoring of each
  supply. Some systems must know that all supplies are
  present and stable before startup and some must know
  if the supplies deviate from safe operating conditions. to externally disable both outputs. The LTC2912 has a
  third option with latching capability and a non-inverted
  overvoltage output. Each part has an internal 6.5V shunt
  regulator allowing the device to be used in a system with
  any supply level. The LTCВ®2912, LTC2913, and LTC2914 supervisors
  respectively monitor single, dual, and quad power supplies for undervoltage and overvoltage with tight 1.5%
  threshold accuracy over temperature. All monitors in the
  multiple-monitor devices share a common undervoltage
  output and a common overvoltage output with a timeout
  period that is adjustable or disabled. Each monitor has
  input glitch rejection to ensure reliable reset operation
  without false or noisy triggering. Basic Operation
  Figure 1 shows a typical application for the LTC2914. Each
  monitored input is compared to a 0.5V threshold. Any
  channel can be configured to monitor both undervoltage
  and overvoltage conditions using a 3-resistor divider. …
