LTC1728HS5-5#TRMPBF

Supervisors Overview

The LTC1728HS5-5 is a triple supply monitor designed for systems with multiple power rails. It features three independent open-drain outputs for individual voltage supervision. The device monitors fixed voltages of 3.086V and 2.338V, alongside an adjustable threshold channel. It operates in automotive-grade environments within a compact 5-pin TSOT-23 package.

Supervisors Feature Summary

• Provides independent monitoring for three distinct power supply rails
• Features open-drain outputs for flexible interface compatibility
• Includes one adjustable voltage threshold channel for custom monitoring

Supervisors Applications

• Monitoring DC/DC converter feedback dividers
• Processor supervisor circuits in multi-voltage systems
• Automotive electronic control unit power integrity checks

Supervisors Procurement Notes

Verify the specific suffix HS5-5 against the official Analog Devices datasheet to confirm the exact voltage thresholds and automotive qualification status. Ensure the TSOT-23 package footprint matches the design requirements. Cross-reference the part number with current manufacturer documentation to validate availability and revision history before finalizing procurement.

Supervisors Selection Notes

Select this component when a system requires simultaneous supervision of three distinct voltage levels within a constrained footprint. The inclusion of an adjustable threshold allows adaptation to non-standard rail voltages. Verify that the open-drain output configuration aligns with the downstream logic requirements of the monitored processor or controller.

Supervisors Part Context

This device belongs to the LTC1727/LTC1728 family of triple supply monitors. These components are engineered for applications requiring comprehensive power management oversight. The series supports various packaging options and threshold configurations to accommodate diverse system architectures and environmental constraints.

Supervisors Replacement Considerations

Consult the official Analog Devices cross-reference guide for verified substitutes. Ensure any replacement maintains the triple-monitor architecture and compatible package dimensions.
