advertisement Versatile Voltage Monitors Simplify Detection of Overvoltage
and Undervoltage Faults вЂ“ Design Note 408
Scott Jackson Introduction
Many modern electronic systems have strict power supply
operating rangesвЂ”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 conп¬Ѓgured to monitor both undervoltage
and overvoltage conditions using a 3-resistor divider. …
