LTC2917IMS-B1#TRPBF

Supervisors Overview

The LTC2917IMS-B1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for low-voltage single-supply monitoring applications. It features selectable voltage thresholds and an integrated watchdog timer. The device operates within a supply voltage range of 1.6V to 5.5V and draws a typical quiescent current of 30µA. It is housed in a 10-lead MSOP package and supports surface-mount installation. The component provides reliable system reset generation based on monitored power rail conditions.

Supervisors Feature Summary

• Offers 27 selectable voltage threshold options for precise monitoring configuration
• Includes an adjustable watchdog timer with timeout reset functionality
• Supports low-power operation with minimal quiescent current consumption

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing reliable voltage supervision
• Industrial control units with strict reset timing requirements

Supervisors Procurement Notes

Verify the exact part number suffix and manufacturer specifications against official Analog Devices documentation before procurement. Confirm availability status as distribution channels may indicate limited stock or restricted supply conditions. Ensure compatibility with your system's voltage levels and package requirements. Cross-reference datasheet parameters to validate performance expectations for your specific application environment.

Supervisors Selection Notes

Select this component when a low-quiescent-current supervisor with configurable thresholds is required. The B1 variant specifies particular threshold settings; verify these match your design needs. Consider the MSOP-10 package size for space-constrained layouts. Evaluate the watchdog timer requirements against your system's fault recovery protocols to ensure adequate protection coverage.

Supervisors Part Context

This part belongs to the LTC2917 series of voltage supervisors from Analog Devices. The series includes variants like LTC2917-A and LTC2917-B, which share core functionalities but differ in threshold configurations. The IMS designation indicates the specific package type and temperature rating. This family is designed for cost-effective and compact power monitoring solutions in modern electronics.

Supervisors Replacement Considerations

Direct substitutes include other LTC2917 variants such as LTC2917IDDB-B1#TRMPBF, provided the package and threshold settings align. Verify pinout compatibility and electrical characteristics before substitution. Generic replacements may lack the specific 27-threshold selection feature or watchdog integration.
