DESCRIPTION
The LTC
®
2913 is a dual input voltage monitor intended for
multiple voltages in a variety of applications. Dual inputs for
each voltage allow monitoring two separate undervoltage
(UV) conditions and two separate overvoltage (OV)
conditions. All monitors share a common undervoltage
output and a common overvoltage output. The LTC2913-1
has latching capability for the overvoltage output. The
LTC2913-2 has functionality to disable both the overvoltage
and undervoltage outputs.
Glitch filtering ensures reliable reset operation without
false or noisy triggering.
The LTC2913 provides a precise, versatile, space-con-
scious, micropower solution for voltage monitoring.
