LTC2963HUDC-1#TRPBF

Supervisors Overview

The LTC2963HUDC-1#TRPBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It features four independent voltage monitoring channels with adjustable thresholds and high accuracy of 0.5%. The device includes a manual reset input, a watchdog timer, and supports open-drain or push-pull outputs. It operates within a supply voltage range of 2.25 V to 5.5 V and consumes 140 uA of quiescent current. The component is housed in a QFN-20 package and functions across an operating temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Provides four independently configurable voltage supervision channels with precise threshold detection.
• Integrates a manual reset input and a built-in watchdog timer for system reliability.
• Offers flexible output configurations including open-drain and push-pull options.

Supervisors Applications

• Multi-rail power supply monitoring in industrial control systems
• Voltage supervision for embedded processor architectures
• System reset management in communication equipment

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing from distributors. Confirm that the HUDC variant meets the required commercial temperature range specifications. Ensure compatibility with existing board layouts due to the QFN-20 footprint dimensions. Cross-reference the manufacturer datasheet for any recent design revisions or lifecycle status updates before finalizing procurement plans.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with high accuracy. The quad-channel architecture reduces bill-of-materials count compared to single-supervisor solutions. Consider the 0.5% accuracy specification for applications demanding tight voltage tolerance margins. Evaluate the trade-off between the 140 uA quiescent current and the need for integrated watchdog functionality.

Supervisors Part Context

This part belongs to the LTC2963 series of supervisory circuits designed for complex multi-voltage environments. It serves as a central monitoring solution for systems requiring robust reset generation and fault detection. The series differentiates itself through configurable thresholds and integrated safety features like watchdog timers, addressing the needs of modern digital systems.
