LTC2909ITS8-2.5#TRPBF

Supervisors Overview

The LTC2909ITS8-2.5#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It monitors three independent supply voltages for under-voltage, over-voltage, and negative voltage conditions. The device features an open-drain reset output with a fixed 200 ms timeout. It operates within a supply voltage range of 1 V to 6 V and maintains a typical accuracy of 1.5%. The component is housed in an 8-pin TSOT-23 package and supports operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors up to three independent power rails simultaneously
• Detects under-voltage, over-voltage, and negative voltage anomalies
• Provides a single open-drain reset signal with fixed delay

Supervisors Applications

• Multi-rail embedded system power supervision
• Industrial control board voltage monitoring
• Telecommunications equipment power integrity checks

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the ITS8 grade meets required temperature specifications. Ensure the 2.5V threshold designation aligns with design requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage lines is required in a compact footprint. The fixed 200 ms reset delay suits applications tolerant of standard startup times. Consider the 1.5% accuracy specification against system tolerance limits. Verify that the open-drain output interface matches the downstream logic requirements.

Supervisors Part Context
