LTC2919CDDB-3.3#TRMPBF

Supervisors Overview

The LTC2919CDDB-3.3#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 6V and features three independent monitoring channels with open-drain outputs. The device provides under-voltage, over-voltage, and negative voltage supervision with high accuracy. It utilizes a 10-WFDFN package with exposed pad for surface mount installation.

Supervisors Feature Summary

• Provides simultaneous monitoring of multiple power rails including under-voltage, over-voltage, and negative voltage conditions
• Features adjustable reset timeout periods to accommodate specific system startup requirements
• Delivers precise voltage threshold detection with low quiescent current consumption

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• Voltage monitoring in portable battery-operated devices
• System reset generation in embedded computing platforms

Supervisors Procurement Notes

Verify the exact suffix #TRMPBF indicates cut tape packaging rather than standard reel quantities. Confirm the C grade temperature range meets operational requirements. Check RoHS compliance status as specified in the latest datasheet revision. Ensure the 10-DFN footprint matches PCB layout constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage lines is required in space-constrained designs. The DFN package offers thermal performance benefits compared to larger packages. Consider the open-drain output configuration compatibility with downstream logic levels. Evaluate the fixed threshold options against application-specific voltage tolerances.

Supervisors Part Context

This part belongs to the LTC2919 family of precision supervisors designed for complex power management applications. It complements other Analog Devices monitoring solutions by offering multi-channel capability in a compact form factor. The series supports various package options to suit different board density requirements.

Supervisors Replacement Considerations

LTC2919IDDB-3.3#TRMPBF offers an extended industrial temperature range. LTC2919CMS-3.3#TRPBF provides an MSOP package alternative. Verify pinout compatibility and electrical specifications before substituting any variant.
