LTC1726ES8-2.5#TRPBF

Supervisors Overview

The LTC1726ES8-2.5#TRPBF is a triple supply monitor and power supervisor integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0V to 7.0V with a typical quiescent current of 20µA. The device features three independent voltage monitoring channels, including two fixed thresholds at 2.5V and 5.0V, and one adjustable threshold. It provides an active-low open-drain reset output with an adjustable delay timer ranging from 1ms to 200ms. A built-in watchdog timer with a timeout period of approximately 140ms ensures system reliability. The component is housed in an 8-pin SOIC package and supports operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates three independent voltage monitoring channels for comprehensive power supervision
• Includes a programmable watchdog timer to detect software malfunctions and trigger system resets
• Features an adjustable reset delay timer to accommodate power-up sequencing requirements
• Provides low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Portable electronic devices requiring multi-rail power management
• Embedded systems needing robust fault detection and recovery mechanisms
• Industrial control units operating in harsh environmental conditions

Supervisors Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required threshold voltages and packaging options. Confirm that the ES8 variant meets the necessary thermal and electrical specifications for the target application environment. Cross-reference the part number with current manufacturer availability status as distribution channels may vary.

Supervisors Selection Notes

Select this component when a compact solution for monitoring multiple voltage rails is required alongside fail-safe watchdog functionality. The fixed 2.5V and 5.0V thresholds simplify design for standard logic levels, while the adjustable channel offers flexibility for custom reference voltages. Ensure the input voltage range aligns with the highest monitored rail and that the reset output drive capability matches the downstream load requirements.

Supervisors Part Context

The LTC1726 belongs to a family of supervisory circuits designed for reliable system protection. This specific model integrates monitoring, reset generation, and watchdog capabilities into a single small-footprint package. It serves as a critical component in ensuring system stability by detecting out-of-tolerance conditions and initiating corrective actions through its reset and watchdog outputs.
