LTC2912IDDB-1#TRMPBF

Supervisors Overview

The LTC2912IDDB-1#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails. It operates within the LTC2912 series and utilizes an 8-DFN (3x2) surface-mount package. The device functions as a simple reset or power-on reset monitor with adjustable or selectable thresholds. It draws a typical operating supply current of 40 uA, ensuring low power consumption during active monitoring. The component supports open-drain or open-collector output configurations and provides a low-active reset signal. It is rated for an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides undervoltage and overvoltage monitoring for a single voltage rail
• Features adjustable or selectable reset threshold voltages
• Offers configurable reset timeout durations
• Supports open-drain or open-collector output logic

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-powered systems needing undervoltage protection
• Industrial control circuits monitoring single power rails
• Embedded systems utilizing adjustable reset thresholds

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates cut tape packaging when sourcing from distributors. Confirm the industrial temperature grade (-40°C to +85°C) matches application requirements. Ensure the DFN-8 footprint aligns with PCB layout specifications. Check RoHS compliance status through official manufacturer documentation before integration.

Supervisors Selection Notes

Select this component when a single-channel supervisor with flexible threshold settings is required. Compare against the HDDB variant if extended temperature ranges up to 125°C are necessary. Consider the ITS8 package option if TSOT-23-8 form factors are preferred for space-constrained designs. Verify that the 40 uA supply current meets system power budget constraints.

Supervisors Part Context

This part belongs to the LTC2912 family of supervisory circuits from Analog Devices. The IDDB-1 designation specifies the industrial temperature range and DFN-8 package configuration. It complements other PMIC solutions like the LTC2910 octal monitor for multi-rail applications. The series focuses on providing reliable reset generation with minimal external component requirements.

Supervisors Replacement Considerations

The LTC2912HDDB-1#TRMPBF serves as a direct pin-compatible alternative offering an extended temperature range up to 125°C. Designers requiring TSOT-23-8 packaging should evaluate the LTC2911ITS8-1#TRMPBF, noting its three-channel capability differs from this single-channel device. Verify threshold compatibility when substituting across different suffix variants.
