LTC2905HTS8#TRPBF

Supervisors Overview

The LTC2905HTS8#TRPBF is a precision dual supply monitor manufactured by Analog Devices Inc. It operates within a voltage range of 1 V to 7 V and features pin-selectable thresholds for monitoring two inputs. The device provides an open-drain output with a reset delay time of 200 ms and maintains an accuracy of 1.5%. It functions within a temperature range of -40°C to +85°C, consumes 65 µA of operating current, and is housed in an SOT-23-8 package.

Supervisors Feature Summary

• Dual input monitoring capability with pin-selectable threshold configurations
• Open-drain reset output with defined 200 ms delay timing
• High precision performance with 1.5% accuracy specification

Supervisors Applications

• Portable instrumentation systems requiring dual rail supervision
• Industrial automation control circuits
• Embedded systems with strict power management requirements

Supervisors Procurement Notes

Verify the specific suffix HTS8 against official Analog Devices documentation to confirm thermal grade and tape-and-reel packaging specifications. Ensure compatibility with target PCB footprint dimensions for the SOT-23-8 package. Cross-reference the part number with authorized distributors to confirm current availability status and lead times prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when precise dual-supervision is required without adjustable programming resistors. The pin-selectable feature simplifies design variations compared to fully programmable alternatives. Consider the 65 µA quiescent current for battery-operated applications. Verify that the 1.5% accuracy meets system tolerance requirements before integration into the final design.

Supervisors Part Context

This component belongs to the LTC2905 series of supervisory circuits designed for low-voltage digital systems. It serves as a compact solution for detecting under-voltage and over-voltage conditions on multiple rails simultaneously. The series is characterized by its small form factor and high accuracy, making it suitable for space-constrained electronic designs.

Supervisors Replacement Considerations

LTC2905ITS8#TRPBF: Different temperature grade (industrial vs. extended). LTC2905CTS8#TRPBF: Different temperature grade (commercial vs. extended). Verify package and electrical parameters match before substitution.
