LTC2912IDDB-3#TRPBF

Supervisors Overview

The LTC2912IDDB-3#TRPBF 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-WFDFN package with exposed pad, suitable for surface-mount applications. The device functions as a simple reset or power-on reset controller with open-drain/open-collector output capabilities. It features adjustable or selectable threshold voltages and offers configurable reset timeouts to accommodate various system timing requirements. Operating across an industrial temperature range of -40°C to +125°C, it maintains a low quiescent current of 40 µA, ensuring efficient power management in space-constrained designs.

Supervisors Feature Summary

• Provides precise supervision for single voltage rails with adjustable or selectable threshold detection
• Features configurable reset timeout periods to match specific system startup or recovery timing needs
• Delivers active-low reset signals via open-drain or open-collector outputs for flexible logic interfacing

Supervisors Applications

• Industrial control systems requiring reliable power monitoring
• Embedded computing platforms needing programmable reset sequencing
• Telecommunications infrastructure equipment with strict uptime requirements

Supervisors Procurement Notes

Verify the exact suffix TRPBF indicates reel packaging when sourcing. Confirm the IDDB variant meets the required industrial temperature specifications for your environment. Ensure the DFN-8 footprint matches your PCB layout constraints. Cross-reference the datasheet for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with customizable thresholds is required. Consider the IDDB package size against available board real estate. Evaluate the 40 µA quiescent current against total system power budgets. Verify that the open-drain output compatibility aligns with the downstream logic levels of the microcontroller or processor being monitored.

Supervisors Part Context

This part belongs to the LTC2912 family of supervisory circuits from Analog Devices. It shares core functionality with other variants like the HDDB and IDDB-1, differing primarily in package type and specific electrical parameter tolerances. The series is categorized under PMIC supervisory circuits, focusing on low-power voltage monitoring solutions for portable and industrial electronics.

Supervisors Replacement Considerations

Direct substitutes include the LTC2912HDDB-3#TRPBF and LTC2912IDDB-1#TRMPBF, provided the channel count and package dimensions are compatible. Verify that alternative parts maintain the same operating temperature range and quiescent current specifications to ensure system reliability.
