LTC2934IDC-2#TRMPBF

Supervisors Overview

The LTC2934IDC-2#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for ultra-low power applications. It features an adjustable supply voltage supervisor with a power-fail output, housed in an 8-lead DFN package. The device operates within a supply voltage range up to 5.5 V and maintains a reset delay time of 200 ms. It draws a typical operating supply current of 500 nA and offers an accuracy of 1.5%. The component supports manual reset functionality and includes open-drain output configuration without a watchdog timer or battery backup switch.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Adjustable threshold voltage for flexible monitoring requirements
• Integrated power-fail detection capability
• Manual reset input for system control

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable voltage supervision
• Industrial equipment with strict power management protocols

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging with cut tape availability through authorized distributors. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the DFN-8 package dimensions match your PCB footprint requirements. Check for any regional distribution restrictions that may affect lead times or availability channels.

Supervisors Selection Notes

Select this component when adjustable voltage monitoring is required alongside low quiescent current specifications. The 1.5% accuracy meets most general-purpose industrial standards. Consider the 200 ms reset delay for timing-sensitive applications. The absence of a watchdog timer simplifies design but requires external implementation if fault recovery is needed. Verify thermal performance within the -40 C to +85 C operating range.

Supervisors Part Context

This part belongs to the LTC2934 series of supervisory circuits from Analog Devices. It shares functional similarities with other variants like the LTC2934IDC-1 and LTC2934ITS8-2, differing primarily in threshold settings and package types. The IDC suffix denotes the DFN-8 package, while the -2 indicates a specific threshold voltage setting within the adjustable family.

Supervisors Replacement Considerations

Direct substitutes include LTC2934IDC-1#TRMPBF for different threshold settings in the same package. For SOT-23-8 packaging, consider LTC2934ITS8-2#TRPBF. Verify pin compatibility and threshold voltage alignment before substitution.
