Typical Application

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 monitoring four separate undervoltage (UV) conditions and four separate overvoltage (OV) conditions. All monitors share a common undervoltage output and a common overvoltage 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 monitoring 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-conscious, micropower solution for voltage monitoring.
