LTC2928CG#TRPBF

Supervisors Overview

The LTC2928CG#TRPBF is a quad-voltage supervisor and power supply sequencer manufactured by Analog Devices Inc. It provides comprehensive power-up and power-down monitoring for up to four independent voltage rails. The device features high-accuracy threshold detection and programmable sequencing timing, allowing precise control over the order and duration of power rail activation. Packaged in a 36-pin SSOP, it integrates cascading capabilities to manage complex multi-rail systems efficiently.

Supervisors Feature Summary

• Provides simultaneous monitoring and sequencing for up to four independent power supply channels
• Features high-accuracy voltage threshold detection for reliable system supervision
• Supports cascading configuration to extend monitoring and sequencing control across multiple devices

Supervisors Applications

• Complex embedded systems requiring strict multi-rail power sequencing
• Industrial equipment with multiple voltage domains
• Telecommunications infrastructure utilizing cascaded power management architectures

Supervisors Procurement Notes

Verify the specific suffix CG#TRPBF against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with existing board layouts for the 36-pin SSOP footprint. Confirm that the required number of monitored rails does not exceed the device's four-channel capacity without additional cascaded units.

Supervisors Selection Notes

Select this component when designing systems that require synchronized power-up and power-down sequences for multiple voltage rails. It is suitable for applications needing precise timing control between different power domains. Consider the 36-pin SSOP package constraints and ensure sufficient PCB space for the required trace routing and decoupling capacitors.
