LTC2909ITS8-2.5#TRM

Supervisors Overview

The LTC2909ITS8-2.5#TRM is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in compact electronic systems. It features three independent monitoring channels with open-drain outputs, housed in an 8-pin SOT-23 package. The device operates within a supply voltage range of 1V to 6V and maintains a low quiescent current of 50µA. It provides a fixed reset delay time of 200ms and ensures high accuracy with a threshold tolerance of 1.5%. The component supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides simultaneous supervision of three distinct input voltages using a single integrated circuit.
• Features configurable thresholds allowing adaptation to various system voltage requirements.
• Delivers active-low reset signals via open-drain outputs for flexible logic interfacing.

Supervisors Applications

• Portable battery-powered devices requiring efficient power management
• Industrial control systems needing reliable voltage supervision
• Communication equipment ensuring stable operation under varying line conditions

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging designation when ordering. Confirm that the selected variant matches the required threshold configuration and output polarity for your design. Ensure compatibility with the target PCB footprint and soldering profile. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Supervisors Selection Notes

Choose this component when multi-rail monitoring is necessary within space-constrained designs. Consider the 50µA quiescent current for battery life optimization. Evaluate the 1.5% accuracy against system tolerance requirements. Verify that the 200ms reset delay aligns with startup sequence timing needs. Compare pinout compatibility if replacing existing supervisor ICs.

Supervisors Part Context

This part belongs to the LTC2909 series of precision voltage monitors. It shares functional similarities with other members like the LTC2909IDDB variants but differs in package type and specific threshold settings. The ITS8 suffix indicates the SOT-23-8 package format, distinguishing it from DFN options.
