LTC2935CDC-2#TRMPBF

Supervisors Overview

The LTC2935CDC-2#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 6.5 V and features selectable threshold voltages including 2.25 V, 2.4 V, 2.55 V, 2.7 V, 2.85 V, 3 V, 3.15 V, and 3.3 V. The device monitors three inputs and provides a push-pull output. It includes a manual reset function with a fixed reset delay time of 200 ms. The component does not contain a watchdog timer or battery backup switch. It is housed in an 8-pin DFN package.

Supervisors Feature Summary

• Provides power-fail output with selectable threshold voltages for precise monitoring
• Includes manual reset capability for system control
• Features push-pull output driver for robust signal transmission

Supervisors Applications

• Monitoring multiple voltage rails in embedded systems

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply conditions. Confirm that the specific suffix matches the required threshold voltage combination and package type. Ensure compatibility with the target operating temperature range and input voltage specifications before integration into the design.

Supervisors Selection Notes

Select this component when multi-input voltage supervision with manual reset is required. The push-pull output eliminates the need for external pull-up resistors. Verify that the available threshold options align with the monitored rail voltages. Consider the DFN package size constraints relative to the PCB layout requirements.

Supervisors Part Context

This part belongs to the LTC2935 series of ultra-low power supply supervisors. The series offers various package options and threshold combinations to suit different application needs. The CDC-2 suffix indicates a specific threshold configuration within the DFN-8 package variant.

Supervisors Replacement Considerations

Check for other LTC2935 variants with compatible thresholds and packages. Verify functional equivalence regarding output type and reset delay if substituting with similar supervisory circuits from other manufacturers.
