LTC2919CDDB-5#TRMPBF

Supervisors Overview

The LTC2919CDDB-5#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within an industrial temperature range of 0°C to 70°C and utilizes a 10-WFDFN package with exposed pad. The device features open-drain or open-collector outputs and provides a minimum reset timeout of 140ms. It monitors three channels, with one fixed threshold at 4.425V and two adjustable thresholds. The component supports low-voltage UV, OV, and negative voltage supervision.

Supervisors Feature Summary

• Provides simultaneous monitoring for up to three independent voltage inputs
• Features configurable thresholds allowing for precise under-voltage and over-voltage detection
• Delivers active-low reset signals via open-drain or open-collector output structure

Supervisors Applications

• Industrial control systems requiring multi-rail power supervision
• Embedded systems needing reliable brown-out protection
• Portable equipment utilizing multiple voltage domains

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the CDDB variant meets the required 0°C to 70°C operating temperature range for your application environment. Ensure compatibility with the 10-DFN footprint during PCB layout review. Cross-reference the datasheet for exact pinout definitions to prevent installation errors.

Supervisors Selection Notes

Select this part when three distinct voltage rails require supervision within a compact surface-mount form factor. The dual adjustable thresholds offer flexibility for custom trip points compared to fixed-only alternatives. Consider the 140ms minimum reset delay to ensure system stability during power transitions. Evaluate the open-drain output capability against the pull-up requirements of the connected microcontroller or logic interface.

Supervisors Part Context

This component belongs to the LTC2919 family of precision supervisors designed for complex power management tasks. It serves as a specialized PMIC solution for applications demanding high accuracy across multiple supply lines. The device integrates essential monitoring functions into a small DFN package, reducing board space compared to discrete comparator solutions.
