LTC2914IGN-1#TRPBF

Supervisors Overview

The LTC2914IGN-1#TRPBF is a supervisory circuit designed to monitor four independent voltage rails simultaneously. It supports both positive and negative voltage monitoring with adjustable under-voltage (UV) and over-voltage (OV) thresholds. The device features a buffered 1V reference output and includes input interference suppression for reliable operation in noisy environments. It operates within a specified temperature range and provides accurate threshold detection across the full operating range.

Supervisors Feature Summary

• Simultaneous monitoring of up to four distinct voltage levels
• Adjustable UV and OV trip points for flexible system configuration
• Capability to monitor two negative voltages in addition to positive rails
• Integrated buffered 1V reference output for external circuitry

Supervisors Applications

• Multi-rail power supply supervision in industrial systems
• Monitoring negative voltage rails in mixed-signal circuits
• System reset generation in complex embedded architectures
• Voltage integrity verification in high-reliability equipment

Supervisors Procurement Notes

Verify the specific suffix IGN-1 against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the tape-and-reel packaging format aligns with your assembly line capabilities. Cross-reference the part number with official Analog Devices documentation to validate availability and lead times through authorized distributors.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails, including potential negative supplies, is required. The adjustable thresholds allow customization for specific system margins without external resistors. Consider the DFN package size and thermal performance if space constraints are critical. Verify that the input interference suppression meets the noise environment of your application.

Supervisors Part Context

This part belongs to the LTC2914 series of multi-voltage supervisors from Analog Devices. It is specifically engineered for applications requiring comprehensive power rail monitoring. The device integrates precision comparators and a reference source into a compact footprint, simplifying board layout compared to discrete solutions. It serves as a central monitoring unit for complex power distribution networks.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the LTC2914IGN-2#TRPBF, which may offer different threshold configurations. Verify functional equivalence regarding voltage monitoring channels and package dimensions before substitution. Consult the manufacturer's cross-reference guide for validated replacements.
