LTC2911IDDB-3

Supervisors Overview

The LTC2911IDDB-3 is a precision triple supply monitor featuring three independent voltage supervision channels and an integrated power-fail comparator. It operates within a wide temperature range of -40°C to +85°C and consumes only 10 µA of quiescent current. The device provides adjustable reset timeouts and utilizes a compact 8-lead DFN package for surface-mount applications.

Supervisors Feature Summary

• Provides precise monitoring for three separate supply rails with high accuracy
• Integrates a dedicated power-fail comparator for system status indication
• Features low power consumption suitable for battery-operated equipment
• Offers adjustable reset timeout durations for flexible timing control

Supervisors Applications

• Portable electronic devices requiring multi-rail power management
• Industrial systems needing reliable voltage supervision under varying temperatures
• Communication infrastructure utilizing multiple voltage domains

Supervisors Procurement Notes

Verify the specific suffix IDDB-3 against official Analog Devices documentation to confirm pinout and threshold specifications. Ensure compatibility with your PCB footprint, as the DFN-8 package requires precise soldering techniques. Confirm availability through authorized distributors, as supply constraints may affect lead times for this component.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltages is required alongside a power-fail signal. Consider its low quiescent current for energy-sensitive designs. Verify that the available thresholds meet your circuit requirements or utilize the adjustable options provided by the device architecture.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits designed for high-accuracy voltage monitoring. It complements other PMIC solutions by offering multi-channel oversight in a small form factor. The series supports various packaging options to accommodate different board space constraints while maintaining consistent performance characteristics.

Supervisors Replacement Considerations

Check for direct substitutes within the LTC2911 family, such as variants with fixed thresholds or different packages. Ensure any replacement maintains the same channel count and power-fail functionality. Verify electrical parameters match the original design requirements before implementation.
