LTC1726IS8-2.5#TRPBF

Supervisors Overview

The LTC1726IS8-2.5#TRPBF is a triple supply monitor and power-supply supervisor integrated circuit manufactured by Analog Devices Inc. It operates within a voltage range of up to 7V and features an adjustable reset delay time with a watchdog timer function. The device provides active-low open-drain outputs for monitoring three distinct input channels, including two fixed thresholds at 3.3V and 5V, alongside one adjustable threshold. Packaged in an MSOP-8 surface-mount format, it supports industrial temperature ranges and includes manual reset capabilities.

Supervisors Feature Summary

• Triple-channel voltage monitoring with dedicated fixed thresholds for 3.3V and 5V systems plus one fully adjustable channel
• Integrated watchdog timer functionality with programmable timeout intervals to detect software malfunctions
• Adjustable reset delay timer allowing customization of the output response time relative to input voltage changes
• Active-low open-drain supervisor output compatible with standard digital logic interfaces

Supervisors Applications

• Multi-rail embedded system power supervision
• Industrial control board voltage monitoring
• Communication equipment power integrity management
• Automotive electronic unit supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape-and-reel configuration. Ensure the component meets required environmental standards such as RoHS compliance before integration. Cross-reference the part number with current distributor availability lists as supply status may vary. Confirm that the operating temperature range aligns with the intended application environment specifications.

Supervisors Selection Notes

Select this component when a single IC solution is required to monitor multiple voltage rails simultaneously. The inclusion of both fixed and adjustable thresholds reduces bill-of-materials complexity compared to discrete comparator solutions. Consider the MSOP-8 footprint constraints during PCB layout planning. Evaluate the need for watchdog functionality if the target system requires automated recovery from processor lockups or communication errors.

Supervisors Part Context

This component belongs to the LTC1726 series of supervisory circuits designed for reliable power management in compact electronic designs. It consolidates multiple monitoring functions into a small surface-mount package, replacing several discrete components. The series is characterized by low quiescent current consumption and high accuracy, making it suitable for battery-operated and space-constrained applications requiring robust fault detection.
