LTC2911HDDB-4#TRMPBF

Supervisors Overview

The LTC2911HDDB-4#TRMPBF is a precision supervisory circuit manufactured by Analog Devices Inc. It features three independent voltage monitors with adjustable thresholds and an integrated power-fail comparator. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical quiescent current of 10µA. It provides push-pull outputs for reset signals and supports adjustable or selectable reset timeouts. The component is housed in an 8-lead DFN package and is rated for operation over an extended temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Three independent precision voltage monitoring channels with adjustable threshold settings
• Integrated power-fail comparator for system status indication
• Adjustable or selectable reset timeout functionality
• Push-pull output drivers for robust signal transmission

Supervisors Applications

• Portable instrumentation systems requiring multi-rail supervision
• Industrial automation control units
• Embedded systems with multiple voltage domains

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF confirms the tape-and-reel packaging format and lead-free (PbF) compliance status. Confirm the 'H' grade designation matches the required extended temperature range specifications for your application environment. Ensure compatibility with existing board layouts regarding the 8-DFN footprint dimensions.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage rails is required alongside power-fail detection. The adjustable thresholds allow customization for various logic levels. Consider the low quiescent current for battery-operated designs. Verify that the DFN package size fits within the available PCB area constraints.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits from Analog Devices. It is designed for applications needing reliable voltage monitoring with minimal power consumption. The series includes variants with different package options and fixed or adjustable thresholds to suit diverse system architectures.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the LTC2911IDDB-4#TRMPBF, noting potential differences in temperature grade or package availability. Verify functional equivalence before substitution.
