LTC2905IDDB#TRPBF

Supervisors Overview

The LTC2905IDDB#TRPBF is a dual-supply voltage monitor manufactured by Analog Devices Inc., designed for systems requiring precise supervision of two independent power rails. It features an adjustable reset delay controlled by an external capacitor, ensuring reliable system recovery from power disturbances. The device operates within a specified temperature range and utilizes an 8-lead DFN package for compact surface-mount integration.

Supervisors Feature Summary

• Simultaneous monitoring of two input voltages with configurable threshold combinations
• Adjustable reset delay via external capacitor to prevent false triggering during power transients
• High accuracy threshold specification maintained across the operating temperature range

Supervisors Applications

• Dual-rail power supply monitoring in embedded systems
• System reset generation for microprocessors with multiple voltage domains
• Power fail detection in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the 'I' grade designation matches required industrial temperature specifications. Cross-reference the manufacturer part number directly with official Analog Devices documentation to ensure authenticity and correct revision status before procurement.

Supervisors Selection Notes

Select this component when dual-channel supervision with customizable timing is required. The adjustable delay feature distinguishes it from fixed-delay alternatives. Ensure the application environment aligns with the industrial temperature rating and that the DFN-8 footprint fits the board layout constraints without compromising thermal performance.

Supervisors Part Context

This part belongs to the LTC2904/LTC2905 family of supervisory circuits. While sharing similar monitoring capabilities, the LTC2905 specifically offers user-adjustable reset delays compared to the fixed delay of its counterpart. It serves as a critical PMIC component for maintaining system integrity in complex multi-voltage architectures.

Supervisors Replacement Considerations

LTC2905CDDB#TRPBF is a commercial grade variant with identical pinout and functionality but different temperature specifications.
