LTC2919IDDB-5#TRPBF

Supervisors Overview

The LTC2919IDDB-5#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It features three independent monitoring channels capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device utilizes an open-drain or open-collector output configuration to signal fault states. It operates within a specified temperature range and is housed in a compact 10-WFDFN package with exposed pad for surface mount installation.

Supervisors Feature Summary

• Supports simultaneous monitoring of multiple power rails including negative voltages
• Provides precise detection of under-voltage and over-voltage thresholds
• Features open-drain/open-collector output for flexible interfacing

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• System reset generation for embedded processors
• Negative voltage protection in mixed-signal circuits

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 'I' grade designation matches required operating temperature ranges for your application environment. Ensure compatibility with the 10-WFDFN footprint during PCB layout review.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required without manual reset functionality. Compare threshold accuracy and quiescent current against other monitors in the family if low power consumption is critical. Verify that the open-drain output drive capability meets the pull-up requirements of the connected logic circuitry.

Supervisors Part Context

This part belongs to the LTC2919 series of precision voltage supervisors. It shares functional similarities with the LTC2909 but offers additional channel flexibility. The IDDB-5 variant specifies the industrial temperature grade and specific threshold settings associated with the -5 suffix code within the product line.

Supervisors Replacement Considerations

LTC2919CDDB-5#TRPBF is listed as a parameter-equivalent alternative.
