LTC2918HMS-B1#TRPBF

Supervisors Overview

The LTC2918HMS-B1#TRPBF is a low-voltage single-supply voltage supervisor manufactured by Analog Devices Inc. It features 27 selectable thresholds and an adjustable watchdog timer with timeout reset functionality. The device operates within a supply voltage range of 1.62V to 5.5V and consumes only 30µA of quiescent current. Packaged in a compact 10-lead MSOP, it provides open-drain or open-collector outputs for system monitoring.

Supervisors Feature Summary

• Integrates 27 selectable voltage thresholds for precise monitoring without external resistors
• Includes an adjustable watchdog timer with timeout reset capability
• Supports both open-drain and open-collector output configurations

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems needing reliable voltage supervision
• Embedded systems with watchdog timer requirements

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the B1 variant matches the required threshold selection options. Check current availability status as distribution may be limited. Ensure compatibility with the target system's voltage levels and package constraints before procurement.

Supervisors Selection Notes

Select this component when a single-supply monitor with integrated threshold selection is required. The 30µA quiescent current makes it suitable for energy-efficient designs. Consider the 10-lead MSOP package size for space-constrained PCB layouts. Verify that the adjustable watchdog timer meets the system's fault recovery timing needs.

Supervisors Part Context

This part belongs to the LTC2917/LTC2918 family of low-voltage supervisors from Analog Devices. These devices are designed for applications requiring precise voltage monitoring with minimal power consumption. The family offers flexibility through selectable thresholds and configurable watchdog timers, addressing common system reliability challenges in portable and industrial electronics.

Supervisors Replacement Considerations

The LTC2917HMS-B1#TRPBF is a confirmed substitute within the same family, offering similar functionality with potentially different threshold characteristics. Verify pinout compatibility and electrical specifications before substitution.
