LTC2911CDDB-3

Supervisors Overview

The LTC2911CDDB-3 is a multi-voltage supervisor IC from Analog Devices Inc., designed for monitoring three distinct power rails. It operates within an ambient temperature range of 0°C to 70°C and features a push-pull, totem-pole output configuration with active-low reset signaling. The device utilizes an 8-WFDFN package with an exposed pad, measuring 3x2 mm. Key electrical thresholds include fixed voltages of 1.683V and 3.086V, alongside one adjustable threshold. It draws a typical operating supply current of 10 µA.

Supervisors Feature Summary

• Provides simultaneous supervision of three independent voltage channels
• Features configurable reset timeout duration for flexible system timing
• Delivers active-low reset signal via push-pull output stage

Supervisors Applications

• Portable equipment requiring multiple battery or rail monitoring
• Embedded systems needing brown-out detection
• Industrial control units with strict power integrity requirements

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout compatibility and threshold settings. Ensure the procurement channel provides genuine components with traceable lot codes. Confirm RoHS compliance status matches project regulatory requirements before finalizing orders.

Supervisors Selection Notes

Select this component when three-channel supervision is required in a compact footprint. The adjustable threshold allows customization for non-standard voltage rails. Verify that the 0°C to 70°C operating range meets environmental constraints. Compare against the ITS8 package variant if smaller surface-mount area is critical.

Supervisors Part Context

This part belongs to the LTC2911 family of precision supervisors. It shares functional similarities with the LTC2919 but differs in package type and specific threshold configurations. The CDDB-3 variant specifically denotes the DFN-8 package with defined fixed thresholds, distinguishing it from other suffixes like ITS8 or TRMPBF variations.
