LTC2919CDDB-3.3#TRPBF

Supervisors Overview

The LTC2919CDDB-3.3#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within an ambient temperature range of 0°C to 70°C and utilizes a 10-WFDFN package with exposed pad. The device features three monitored voltage channels, including two adjustable thresholds and one fixed threshold at 2.921V. It provides a low-active reset output with a minimum reset timeout of 140ms. The component supports open-drain or open-collector outputs for flexible system integration.

Supervisors Feature Summary

• Provides simultaneous monitoring of up to three independent voltage inputs
• Features configurable dual adjustable thresholds alongside a fixed reference channel
• Generates a low-active reset signal upon detection of under-voltage or over-voltage conditions

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Battery management unit voltage integrity verification
• Industrial control board power sequencing protection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the CDDB variant corresponds to the commercial temperature grade (0°C to 70°C) rather than the extended IDDB industrial grade. Ensure the DFN-10 footprint matches the PCB layout requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing circuits requiring supervision of multiple distinct voltage rails from a single IC. The dual-adjustable feature allows customization for specific brown-out or over-voltage limits. Consider the 140ms minimum reset delay when determining compatibility with fast-switching load dynamics in the target application environment.

Supervisors Part Context

This part belongs to the LTC2919 family of precision supervisors. It shares functional similarities with the LTC2912 but offers enhanced multi-channel capability. The device integrates high-accuracy comparators to ensure reliable fault detection across varying operating conditions without requiring external hysteresis components.
