LTC2964HUDC#TRPBF

Supervisors Overview

The LTC2964HUDC#TRPBF is a quad configurable supervisor IC from Analog Devices, housed in a 20-lead UTQFN package. It monitors four independent voltage rails with 0.5% accuracy across a supply range of 2.25V to 5.5V. The device features adjustable thresholds, manual reset capability, and open-drain or push-pull outputs. It operates within a temperature range of -40°C to +125°C and consumes 140µA of quiescent current.

Supervisors Feature Summary

• Monitors four independent input voltages simultaneously
• Provides high-accuracy supervision with 0.5% threshold precision
• Supports flexible output configurations including open-drain and push-pull modes
• Includes manual reset functionality for system control

Supervisors Applications

• Multi-rail power monitoring in industrial systems
• Voltage supervision for embedded computing platforms
• Power integrity management in communication equipment

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the UTQFN-20 footprint matches your PCB layout requirements. Ensure the operating voltage range aligns with your monitored rails. Check RoHS compliance documentation for regulatory adherence. Validate the manufacturer part number against official Analog Devices catalogs to avoid counterfeit components.

Supervisors Selection Notes

Choose this component when simultaneous monitoring of four distinct voltage lines is required. The 0.5% accuracy suits applications demanding precise fault detection. The wide operating temperature range supports harsh environments. Consider the manual reset feature if external intervention is needed during fault conditions. Evaluate the low quiescent current for battery-sensitive designs.
