LTC2909CTS8-3.3#TRMPBF

Supervisors Overview

The LTC2909CTS8-3.3#TRMPBF is a precision voltage monitor manufactured by Analog Devices Inc., designed for supervising multiple power rails in compact electronic systems. It features three monitored inputs capable of detecting under-voltage, over-voltage, and negative voltage conditions with high accuracy. The device operates within a supply voltage range of 2.7 V to 6 V and consumes a low quiescent current of 50 µA, making it suitable for battery-powered applications. It provides an open-drain reset output with a fixed 200 ms delay and includes manual reset functionality. Packaged in an SOT-23-8 surface-mount case, it supports industrial temperature ranges.

Supervisors Feature Summary

• Monitors up to three independent voltage inputs simultaneously for under-voltage, over-voltage, and negative voltage detection
• Provides precise threshold monitoring with 1.5% accuracy across the operating temperature range
• Features manual reset capability allowing external control over the reset state via dedicated pin
• Delivers active-low open-drain reset signal with configurable timeout delay for system protection

Supervisors Applications

• Portable handheld devices requiring multi-rail power supervision
• Battery-operated equipment needing low quiescent current monitoring
• Industrial control systems with strict voltage tolerance requirements
• Embedded systems utilizing single-ended or differential input monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package marking matches LTC2909CTS8-3.3#TRMPBF identifiers. Check RoHS compliance documentation for environmental standards adherence. Validate datasheet revision against current manufacturing specifications. Ensure storage conditions maintain moisture sensitivity level integrity prior to assembly.

Supervisors Selection Notes

Select this variant when precise triple-input monitoring is required in space-constrained designs. Consider the SOT-23-8 package for surface-mount compatibility with standard PCB layouts. Evaluate the 50 µA quiescent current against total system power budgets. Verify that the 200 ms reset delay aligns with system startup timing requirements. Confirm manual reset pin availability meets design flexibility needs.
