LTC2917IMS-A1#TRPBF

Supervisors Overview

The LTC2917IMS-A1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage with selectable thresholds and includes an adjustable watchdog timer. The device operates on a single supply voltage ranging from 1.6V to 5.5V, consuming only 30µA of quiescent current. It features an open-drain reset output with a fixed 200ms delay and is housed in a 10-lead MSOP package.

Supervisors Feature Summary

• Provides voltage supervision with 27 selectable threshold options for precise monitoring
• Integrates an adjustable watchdog timer for system fault recovery
• Operates efficiently at low voltages with minimal power consumption

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing efficient voltage monitoring
• Embedded controllers utilizing watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix A1 against official documentation to confirm the exact threshold configuration. Ensure the MSOP-10 package matches your PCB footprint requirements. Confirm that the operating temperature range aligns with your application environment before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel monitor with configurable thresholds is required. The integrated watchdog timer simplifies design compared to discrete solutions. Consider the 30µA quiescent current for battery life optimization. Verify compatibility with the target system's logic levels due to the open-drain output structure.

Supervisors Part Context

This part belongs to the LTC2917 series of low-voltage supervisors. It shares core functionalities with other variants in the family but differs in package type and specific threshold settings. The IMS-A1 designation indicates a specific trim version within the broader product line.
