LTC2935CDC-4#TRMPBF

Supervisors Overview

The LTC2935CDC-4#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 features eight selectable threshold voltages: 1.6 V, 1.72 V, 1.84 V, 1.96 V, 2.08 V, 2.2 V, 2.32 V, and 2.44 V. The device monitors one input channel with an accuracy of 1.5% and includes power-fail detection capabilities. It offers manual reset functionality with a reset delay time of 200 ms. The component draws a typical operating supply current of 500 nA and functions reliably across a temperature range from 0°C to +70°C.

Supervisors Feature Summary

• Provides ultra-low power consumption suitable for battery-operated applications
• Integrates selectable threshold voltages for flexible monitoring configurations
• Includes dedicated power-fail output for system protection

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage supervision
• Embedded systems with multiple voltage rails

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape-and-reel packaging with limited availability constraints. Confirm RoHS compliance status through official documentation before integration. Ensure the selected threshold voltage matches the target supply rail requirements. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Validate package dimensions against PCB footprint specifications during design review.

Supervisors Selection Notes

Select this part when a single-channel supervisor with configurable thresholds is required. Compare against other LTC2935 variants based on package type and temperature grade. Consider the 500 nA quiescent current for energy-sensitive designs. Verify that the 200 ms reset delay meets system startup timing requirements. Ensure the 5.5 V maximum supply voltage covers the highest expected input level.

Supervisors Part Context

This component belongs to the LTC2935 series of ultra-low power supervisors. It shares functional similarities with other members like the LTC2935ITS8-4#TRMPBF but differs in package style and operating temperature range. The CDC variant specifically utilizes an 8-DFN package. It serves as a critical element in power management integrated circuits (PMIC) for ensuring stable operation under varying load conditions.

Supervisors Replacement Considerations

Direct substitutes include other LTC2935 variants such as LTC2935CTS8-4#TRMPBF or LTC2935ITS8-4#TRMPBF, provided package and temperature specifications align. Verify pin compatibility and electrical parameters before substitution.
