LTC2911CDDB-3#TRMPBF

Supervisors Overview

The LTC2911CDDB-3#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in electronic systems. It features three independent voltage monitor channels with a push-pull or totem pole output configuration, ensuring robust signal integrity for reset generation. The device operates within an industrial temperature range of 0°C to 70°C and consumes a low operating supply current of 10 µA, making it suitable for power-sensitive applications. Packaged in an 8-lead DFN (3x2 mm) surface-mount package, this component provides reliable power-fail detection and reset functionality for complex multi-rail designs.

Supervisors Feature Summary

• Three-channel voltage monitoring capability for comprehensive system supervision
• Push-pull output stage for strong drive capability and noise immunity
• Low quiescent current consumption for energy-efficient operation
• Compact surface-mount packaging for space-constrained PCB layouts

Supervisors Applications

• Multi-rail power supply monitoring in industrial equipment
• System reset generation in embedded computing platforms

Supervisors Procurement Notes

Verify the exact suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm that the DFN-8 package dimensions match your PCB footprint requirements. Ensure compatibility with your system's voltage thresholds and reset timing specifications. Check for any recent manufacturing changes or obsolescence notices from Analog Devices. Validate RoHS compliance status if required by your regional regulations.

Supervisors Selection Notes

Select this component when three independent voltage monitors are required with active-high or active-low reset outputs. Consider the 10 µA supply current for battery-operated or low-power designs. The DFN-8 package offers thermal performance advantages over larger packages. Verify that the monitored voltage levels align with your system's rail specifications. Evaluate the need for adjustable versus fixed threshold voltages based on design flexibility requirements.
