LTC2918IMS-A1#TRPBF

Supervisors Overview

The LTC2918IMS-A1#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent input channels with adjustable thresholds, enabling detection of under-voltage and over-voltage conditions. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical quiescent current of 40µA. It provides open-drain reset outputs with a programmable delay and includes a manual reset input. Packaged in an 8-lead MSOP, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Triple-channel voltage monitoring with individually adjustable threshold levels
• Open-drain reset output with configurable delay timer
• Manual reset input capability for system control
• Low power consumption suitable for battery-operated applications

Supervisors Applications

• Portable electronic devices requiring multi-rail supervision
• Industrial control systems with strict voltage tolerance requirements
• Embedded computing platforms needing reliable power-fail detection

Supervisors Procurement Notes

Verify the specific suffix A1 against official Analog Devices documentation to confirm threshold configurations. Ensure compatibility with target PCB footprint and thermal requirements. Confirm availability status through authorized distributors as supply may be limited. Cross-reference pinout assignments with schematic designs prior to implementation.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage lines is required. Consider the adjustable threshold feature for custom voltage trip points. Evaluate the low quiescent current for energy efficiency constraints. Verify that the MSOP package fits the available board space and assembly capabilities.
