LTC2919 - Negative Voltage Monitor

Datasheet Summary

Description

The LTC®2919 is a triple/dual input monitor intended for a variety of system monitoring applications.

Polarity selection and a buffered reference output allow the LTC2919 to monitor positive and negative supplies for undervoltage (UV) and overvoltage (OV) conditions.

Features
