LTC2915HDDB-1#TRMPBF

Supervisors Overview

The LTC2915HDDB-1#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides an open-drain reset output. The device features adjustable threshold voltages with 27 selectable options, ensuring precise power management. It includes a fixed reset delay time of 200 ms to prevent false triggering during power transitions. The component operates within a supply voltage range up to 5.5 V and maintains an accuracy of 1.5%. It is housed in an 8-lead DFN package and supports surface mount installation.

Supervisors Feature Summary

• Provides voltage supervision for a single monitored input channel
• Offers 27 factory-selected threshold voltage combinations for flexible configuration
• Generates a low-active reset signal via an open-drain output structure
• Incorporates a fixed 200 ms reset delay timer to ensure stable operation

Supervisors Applications

• Monitoring main power rails in embedded systems
• Supervising battery-powered devices requiring precise voltage thresholds
• Industrial control circuits needing reliable power-fail detection
• Consumer electronics with strict power-up sequencing requirements

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF to confirm the tape-and-reel packaging format and lead-free compliance status. Ensure compatibility with the target PCB footprint, specifically the 8-lead DFN package dimensions. Cross-reference the manufacturer's latest datasheet for any updates on operating temperature ranges or electrical characteristics before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with adjustable thresholds is required. The open-drain output allows for easy interfacing with various logic families. Consider the 200 ms fixed delay against system timing requirements. Verify that the maximum supply voltage of 5.5 V aligns with the highest expected input voltage in the application design.

Supervisors Part Context

This part belongs to the LTC2915 series of precision voltage supervisors from Analog Devices. The series offers multiple package options including SOT-23 and DFN variants. The HDDB suffix indicates the specific 8-lead DFN package type. These components are designed for applications requiring high accuracy and low quiescent current in compact form factors.

Supervisors Replacement Considerations

Check the official Analog Devices cross-reference list for verified substitutes. Ensure any replacement matches the 8-DFN package outline and pinout. Verify that alternative parts support the same 27 threshold options and 200 ms delay characteristics if those parameters are critical to the design.
