LTC2914
Quad UV/OV
Positive/Negative
Voltage Monitor
Description
The LTC®2914 is a quad input voltage monitor intended for
monitoring multiple voltages in a variety of applications.
Dual inputs for each monitored voltage allow monitor-
ing four separate undervoltage (UV) conditions and four
separate overvoltage (OV) conditions. All monitors share
a common undervoltage output and a common overvolt-
age output. The LTC2914-1 has latching capability for the
overvoltage output. The LTC2914-2 has functionality to
disable both the overvoltage and undervoltage outputs.
Polarity selection and a buffered reference allow monitor-
ing up to two separate negative voltages. A three-state
input pin allows setting the polarity of two inputs without
requiring any external components. Glitch filtering ensures
reliable reset operation without false or noisy triggering.
The LTC2914 provides a precise, versatile, space-con-
scious, micropower solution for voltage monitoring.
