LTC2919 - Negative Voltage Monitor

General 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.

Key Features

  • nn Two Low Voltage Adjustable Inputs (0.5V) nn Accurate UVLO Provides a Third Monitor Input nn Open-Drain RST, OUT1 and OUT2 Outputs nn Pin Selectable Input Polarity Allows Negative, UV and OV Monitoring nn Guaranteed Threshold Accuracy: ±1.5% nn 6.5V Shunt Regulator for High Voltage Operation nn Low 50µA Quiescent Current nn Buffered 1V Reference for Negative Supply Offset nn Input Glitch Rejection nn Adjustable Reset Timeout Period nn Selectable Internal Timeout Saves Components nn Outputs Gua.
