LTC2928IG#TRPBF

Supervisors Overview

The LTC2928IG#TRPBF is a four-channel cascadable power supply sequencer and high-accuracy supervisor manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 36V and features adjustable sequencing thresholds. The device supports precise timing control with programmable delays and includes integrated brown-out detection for each channel. Packaged in a 36-pin SSOP, it provides reliable monitoring and sequencing for complex multi-rail power systems.

Supervisors Feature Summary

• Four independent channels for cascaded power supply sequencing
• High-accuracy voltage supervision with adjustable thresholds
• Programmable delay times for controlled power-up and power-down sequences
• Integrated brown-out detection for each monitored rail

Supervisors Applications

• Multi-rail server and storage system power management
• Industrial equipment requiring strict power sequencing
• Telecommunications infrastructure power supplies
• Test and measurement instruments with multiple voltage rails

Supervisors Procurement Notes

Verify the specific suffix 'IG' indicates the industrial temperature grade (-40°C to +85°C) and 'TRPBF' denotes tape-and-reel packaging. Confirm that the 36-pin SSOP package matches your PCB footprint requirements. Ensure compatibility with your system's voltage levels before integration.

Supervisors Selection Notes

Select this component when four independently sequenced and supervised rails are required. It is suitable for applications needing precise timing control between power rails. Consider the cascadable nature if more than four channels are needed by linking multiple units. Verify input voltage ranges match your system design.

Supervisors Part Context

This part belongs to the LTC2928 family of multichannel power supply sequencers and supervisors. It is designed to replace discrete logic solutions for power sequencing, offering higher accuracy and reduced board space. The series is commonly used in systems where power rail order and stability are critical for proper operation.

Supervisors Replacement Considerations

Direct substitutes may include other Analog Devices multichannel sequencers such as the LTC2929 or LTC2927, depending on channel count and package requirements. Verify pinout compatibility and electrical specifications before substitution.
