DESCRIPTION

· The LTC2914 is a quad input voltage monitor designed for monitoring multiple voltages in various applications.

· It features dual inputs for each monitored voltage, allowing it to monitor four separate undervoltage (UV) and overvoltage (OV) conditions.

· The device includes a common UV and OV output, with the LTC2914-1 offering latching capability for the OV output and the LTC2914-2 allowing the disabling of both UV and OV outputs.

· It can monitor up to two separate negative voltages with polarity selection and a buffered reference.

· A three-state input pin enables setting the polarity of two inputs without external components, and glitch filtering ensures reliable reset operation.

FEATURES

· Monitors four voltages simultaneously with adjustable UV and OV trip values.

· Guaranteed threshold accuracy of ±1.5% of monitored voltage over temperature.

· Input glitch rejection and monitoring of up to two negative voltages.

· Buffered 1V reference output and adjustable reset timeout with timeout disable.

· Low quiescent current of 62µA and open-drain OV and UV outputs.

· Guaranteed OV and UV for VCC ≥ 1V, available in 16-Lead SSOP and DFN packages.

APPLICATIONS

· Suitable for desktop and notebook computers, network servers, and core and I/O voltage monitors.

· Ideal for monitoring multiple supply voltages with a 10% tolerance, including 5V, 3.3V, 2.5V, and 1.8V.
