LTC2919IDDB-3.3#TRPBF

Supervisors Overview

The LTC2919IDDB-3.3#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and is housed in a compact 10-WFDFN (3x2) package with an exposed pad. The device features open-drain or open-collector outputs and provides a minimum reset timeout of 140ms. It supports monitored voltage thresholds including fixed options like 2.921V and adjustable settings, making it suitable for supervising multiple power rails in space-constrained applications.

Supervisors Feature Summary

• Provides simultaneous supervision of three independent voltage inputs for comprehensive power monitoring
• Features configurable reset timeouts to accommodate various system startup and shutdown requirements
• Utilizes low-profile surface-mount packaging designed for high-density circuit board layouts

Supervisors Applications

• Industrial control systems requiring multi-rail power supervision
• Telecommunications infrastructure equipment
• Automotive electronic control units

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel configuration against official Analog Devices documentation to ensure compatibility with automated assembly processes. Confirm that the industrial temperature grade meets environmental specifications for the intended deployment location. Cross-reference the exact part number with current manufacturer availability lists as supply status may vary.

Supervisors Selection Notes

Select this component when precise monitoring of multiple voltage domains is required within a limited footprint. Ensure the chosen threshold voltages align with the specific rails being supervised. Consider the open-drain output capability for interfacing with various logic families. Verify that the thermal performance of the DFN package suits the ambient operating conditions.

Supervisors Part Context

This part belongs to the LTC2919 series of precision supervisors from Analog Devices. It shares functional similarities with other members of the family but differs in package type and specific threshold configurations. The IDDB variant specifically denotes the industrial temperature range and DFN packaging, distinguishing it from commercial grade or MSOP packaged alternatives.

Supervisors Replacement Considerations

Direct substitutes include other LTC2919 variants such as LTC2919CDDB-3.3#TRMPBF or LTC2919CMS-3.3#TRPBF, provided the package and temperature grade differences are acceptable for the design.
