LTC2963HUDC-1#PBF

Supervisors Overview

The LTC2963HUDC-1#PBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.25 V to 5.5 V and features adjustable threshold voltages for monitoring up to four independent inputs. The device provides open-drain and push-pull output types, includes a manual reset input, and integrates a watchdog timer function. It maintains an accuracy of 0.5% with a reset delay time of 200 ms. Designed for surface mount installation in a QFN-20 package, it supports an operating temperature range from -40°C to +85°C and draws a typical supply current of 140 µA.

Supervisors Feature Summary

• Monitors four independent voltage rails with high precision
• Configurable thresholds allow flexible system protection settings
• Integrates watchdog timer for automated fault recovery

Supervisors Applications

• Multi-rail power supply supervision in industrial systems
• Embedded controller reset management
• Watchdog timer implementation in microprocessor systems

Supervisors Procurement Notes

Verify the specific suffix and manufacturer part number against official Analog Devices documentation to ensure correct configuration. Confirm availability status as distribution channels may indicate limited stock or restricted sales regions. Validate package type and temperature grade match design requirements before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required with precise threshold control. Consider the QFN-20 package constraints and thermal performance for the target application environment. Ensure the supply voltage range aligns with the system's power architecture and that the output drive capabilities meet downstream logic requirements.

Supervisors Part Context

This part belongs to the LTC2963 series of supervisory circuits designed for complex power management applications. It offers enhanced configurability compared to single-channel supervisors, allowing designers to consolidate multiple monitoring functions into a single integrated circuit. The series supports various output configurations and timing parameters suitable for robust system protection.

Supervisors Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible alternatives within the same family. Verify functional equivalence regarding threshold adjustability and watchdog features before substitution.
