LTC2919HDDB-5#TRPBF

Supervisors Overview

The LTC2919HDDB-5#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 +125°C and is housed in a 10-pin DFN package. The device monitors three inputs, featuring a fixed threshold of 5V for one channel and adjustable thresholds for the remaining two. It provides active-low reset outputs with open-drain configuration and includes a minimum reset timeout of 140ms.

Supervisors Feature Summary

• Supports simultaneous monitoring of three voltage rails or dual inputs with negative voltage capability
• Features high-precision voltage detection with fixed and adjustable threshold options
• Provides active-low reset signal with configurable timeout delay

Supervisors Applications

• Industrial system power supervision
• Automotive electronic control unit monitoring
• Multi-rail server and communication equipment protection

Supervisors Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging. Confirm the HDDB variant meets the required -40°C to +125°C industrial temperature grade. Ensure the 5V fixed threshold aligns with the specific rail being monitored. Cross-reference the 10-DFN footprint with the target PCB layout.

Supervisors Selection Notes

Select this part when precise monitoring of three distinct voltage levels is required in harsh environments. The adjustable thresholds allow customization for non-standard rails. The wide operating temperature range suits automotive and industrial applications where standard commercial grades are insufficient.

Supervisors Part Context

This component belongs to the LTC2919 family of precision supervisors. It shares architectural similarities with the LTC2909 but offers enhanced precision and additional input channels. The DFN package provides a compact solution for space-constrained designs requiring reliable power management supervision.
