LTC2914CGN-2#TRPBF

Supervisors Overview

The LTC2914CGN-2#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring four independent voltage rails simultaneously. It supports both positive and negative voltage monitoring with adjustable threshold voltages. The device features an open-drain output type and operates within a supply voltage range of up to 7 V. It provides a reset delay time of 8.5 ms and maintains a threshold accuracy of ±1.5% over the operating temperature range. The component consumes a typical working power supply current of 70 uA and is housed in a 16-SSOP package suitable for surface mount installation.

Supervisors Feature Summary

• Simultaneous monitoring of four independent voltage inputs
• Supports both positive and negative voltage supervision
• Adjustable threshold voltage settings for flexible application
• High precision accuracy across the full operating temperature range

Supervisors Applications

• Multi-rail power supply monitoring systems
• Industrial control board voltage supervision
• Telecommunications equipment power integrity checks
• Embedded system voltage fault detection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the CGN-2 variant matches the required SSOP package and temperature grade. Ensure the adjustable threshold configuration aligns with the target voltage levels. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components. Check regional availability as distribution may vary.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The adjustable thresholds allow customization for various standard and non-standard voltage levels. The low quiescent current makes it suitable for battery-backed or energy-efficient designs. Verify that the open-drain output interface is compatible with the downstream logic or microcontroller input requirements.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. It is specifically engineered for applications requiring robust voltage monitoring without complex external components. The series offers multiple package options, with the CGN-2 variant providing a 16-lead SSOP footprint. It serves as a critical protection element in modern electronic systems against under-voltage and over-voltage conditions.

Supervisors Replacement Considerations

Direct replacements include other parts from the LTC2914 family such as the LTC2914CGN-2#PBF for tube packaging. Alternative quad-channel monitors from Analog Devices should be evaluated for pin compatibility and electrical specifications. Ensure any substitute maintains the same adjustable threshold capability and open-drain output structure.
