LTC2934IDC-1#TRMPBF

Supervisors Overview

The LTC2934IDC-1#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and consumes a typical quiescent current of 500 nA. The device features an adjustable threshold voltage with an accuracy of 1.5%. It provides a manual reset function with a fixed reset delay time of 200 ms. The component includes power-fail detection capabilities and utilizes an open-drain output type. It is housed in a DFN-8 package and supports surface mount installation.

Supervisors Feature Summary

• Ultra-low power consumption with 500 nA operating current
• Adjustable threshold voltage for flexible monitoring applications
• Integrated power-fail detection output
• Manual reset capability with defined delay timing

Supervisors Applications

• Portable battery-powered equipment requiring low standby current

• Industrial control circuits with manual reset requirements

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special order constraints. Confirm RoHS compliance details through official documentation before procurement. Ensure the DFN-8 package variant matches your PCB footprint requirements. Cross-reference the specific suffix #TRMPBF to confirm tape and reel packaging specifications. Validate that the adjustable threshold configuration meets your system's voltage monitoring needs.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for battery life extension. Choose the adjustable threshold version if the monitored voltage level varies or requires customization beyond fixed options. Consider the DFN-8 package for compact board space constraints. Verify that the open-drain output interface is compatible with the downstream logic levels. Ensure the 200 ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This part belongs to the LTC2934 series of ultra-low power supervisory circuits from Analog Devices. It is designed for applications where power efficiency and precise voltage monitoring are paramount. The series typically offers various package options and threshold configurations to suit different design constraints while maintaining consistent low-power performance characteristics across the family.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same series, such as other LTC2934 variants with fixed thresholds. Verify that any substitute maintains the 500 nA quiescent current specification. Ensure the replacement supports the required 5.5 V maximum input voltage. Confirm compatibility with the DFN-8 package if physical footprint retention is necessary.
