LTC2919HDDB-3.3#TRPBF

Supervisors Overview

The LTC2919HDDB-3.3#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to 125°C and is housed in a 10-pin DFN package with exposed pad. The device features open-drain active-low reset outputs and supports undervoltage, overvoltage, and negative voltage monitoring. It includes a manual reset input and offers adjustable or selectable thresholds for flexible system supervision.

Supervisors Feature Summary

• Supports simultaneous monitoring of three independent voltage rails including negative voltages
• Provides precise threshold detection for undervoltage, overvoltage, and negative supply conditions
• Features open-drain active-low reset outputs compatible with various logic families
• Includes a manual reset input pin for external control of the reset state

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• Negative voltage monitoring for dual-supply operational amplifier circuits
• System reset generation in embedded processors requiring multiple voltage checks
• Automotive electronics requiring extended temperature range reliability

Supervisors Procurement Notes

Verify the exact suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HDDB variant meets the required -40°C to 125°C operating temperature range for your specific application environment. Ensure the 10-DFN footprint matches your PCB layout constraints. Cross-reference the datasheet for electrical characteristics relevant to your supply voltages.

Supervisors Selection Notes

Select this component when triple-channel supervision is required with high precision. Consider the DFN package size if space is limited on the PCB. Verify that the open-drain output configuration aligns with your microcontroller or logic input requirements. Check if the manual reset feature is necessary for your system startup sequence.
