LTC1726IS8-5

Supervisors Overview

The LTC1726IS8-5#TR is a micropower triple supply monitor and processor supervisor manufactured by Analog Devices. It features three independent voltage detectors with adjustable reset thresholds, an open-drain active-low reset output, and an integrated watchdog timer with a fixed timeout period. The device operates within a supply voltage range of 1.0V to 7.0V and draws only 20µA of quiescent current. Housed in an 8-lead SOIC package, it provides reliable system supervision for multi-rail applications.

Supervisors Feature Summary

• Triple voltage monitoring channels with individually adjustable reset thresholds
• Integrated watchdog timer with fixed timeout interval for fault recovery
• Open-drain active-low reset output compatible with various logic families
• Micropower operation with low quiescent current consumption

Supervisors Applications

• Multi-voltage rail supervision in embedded systems
• Processor reset generation for microcontrollers and FPGAs
• Watchdog timer implementation in industrial control units
• Battery-powered equipment requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix #TR indicates tape-and-reel packaging versus bulk options. Check for recent discontinuation notices or lifecycle status updates from Analog Devices prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring with distinct threshold levels. The adjustable reset pins allow customization for non-standard supply voltages. Ensure the required watchdog timeout duration aligns with the application's operational cycle timing constraints.

Supervisors Part Context

This part belongs to the LTC1726 family of supervisory circuits designed for precision voltage monitoring. It complements other Analog Devices power management solutions by providing dedicated reset generation and fault detection capabilities for complex digital systems requiring robust power integrity assurance.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference parts. Potential alternatives may include the LTC1727 series or similar triple-supply monitors from the same manufacturer family, ensuring pinout and functional compatibility.
