LTC1726ES8-2.5#PBF

Supervisors Overview

The LTC1726ES8-2.5#PBF is a triple supply monitor and microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within an input voltage range of up to 7 V and functions reliably across a temperature range of -40°C to +85°C. The device features three monitored inputs with thresholds set at 3.3 V, 5 V, and adjustable levels. It provides active low, open-drain outputs and includes an adjustable reset delay time along with a watchdog timer function. The circuit draws a typical operating supply current of 20 uA and is housed in an SOIC-8 package.

Supervisors Feature Summary

• Monitors three distinct power supply rails simultaneously for system integrity
• Integrates a configurable watchdog timer to detect software malfunctions
• Provides active low open-drain reset signals for microprocessor control

Supervisors Applications

• Systems requiring supervision of multiple independent voltage rails
• Microprocessor monitoring circuits with adjustable reset timing
• Embedded systems utilizing configurable watchdog protection mechanisms

Supervisors Procurement Notes

Verify the specific suffix and package configuration against official datasheets before procurement. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure compatibility with existing board layouts and thermal requirements. Cross-reference pinouts to prevent integration errors during assembly.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltages is required within a single package. Consider the fixed thresholds of 3.3 V and 5 V alongside the adjustable channel for flexible design. Evaluate the 20 uA quiescent current against battery life constraints. Verify that the SOIC-8 footprint meets PCB space limitations.

Supervisors Part Context

This part belongs to the LTC1726 series of supervisory circuits designed for complex embedded environments. It consolidates multiple monitoring functions into a compact form factor, reducing component count compared to discrete solutions. The series supports various threshold combinations to accommodate different logic families and power architectures.

Supervisors Replacement Considerations

Consult official documentation for direct cross-references. Alternative parts must match the triple-input capability and SOIC-8 package. Verify equivalent watchdog functionality and output drive characteristics before substitution.
