LTC2909CTS8-5#TRPBF

Supervisors Overview

The LTC2909CTS8-5#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features three independent inputs capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device operates with a maximum supply voltage of 6 V and draws a typical quiescent current of 50 uA. It provides a reset delay time of 200 ms and utilizes an open-drain output configuration. The component is housed in an SOT-23-8 surface-mount package and maintains an accuracy of 1.5% across its operating range.

Supervisors Feature Summary

• Monitors up to three independent voltage inputs for under-voltage, over-voltage, and negative voltage anomalies
• Provides precise threshold detection with 1.5% accuracy without requiring manual reset functionality
• Features low power consumption suitable for battery-operated systems with minimal quiescent current draw

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Battery management systems requiring negative voltage protection
• Industrial control circuits needing reliable under-voltage and over-voltage alerts

Supervisors Procurement Notes

Verify the exact suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm that the CTS8-5 designation matches the required SOT-23-8 package and 5V reference or input configuration. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability, as availability may be restricted.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of three distinct voltage lines within a 6V limit. Ensure the application benefits from the open-drain output compatibility with various logic families. Consider the 200ms reset delay for noise immunity requirements. Verify that the SOT-23-8 footprint aligns with the PCB layout constraints and that the 50uA quiescent current meets the system's power budget.
