LTC2934CDC-1#TRMPBF

Supervisors Overview

The LTC2934CDC-1#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features an adjustable threshold voltage with 1.5% accuracy. The device provides a manual reset function, a fixed 200 ms reset delay, and power-fail detection capabilities. It draws a typical operating current of 500 nA and utilizes an open-drain output. The component is housed in an 8-lead DFN package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Adjustable voltage threshold monitoring with high accuracy
• Integrated manual reset capability for system control

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation systems
• Embedded controllers needing reliable power supervision

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm that the CDC variant matches the required industrial temperature range and package dimensions for your PCB layout. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Supervisors Selection Notes

Select this component when an adjustable threshold and manual reset are required alongside minimal quiescent current. Ensure the input voltage remains within the 2.0 V to 5.5 V operational window. Verify that the open-drain output configuration aligns with the pull-up requirements of the connected microcontroller or logic interface.

Supervisors Part Context

This part belongs to the LTC2934 series of ultra-low power supervisors. It shares functional similarities with other members like the LTC2935 but differs in specific package options and threshold configurations. The series is designed for applications where power efficiency and precise voltage monitoring are critical constraints.

Supervisors Replacement Considerations

Consult the Analog Devices cross-reference guide for verified substitutes. Direct replacements must maintain the 8-DFN footprint and compatible electrical characteristics.
