LTC2911IDDB-5

Supervisors Overview

The LTC2911IDDB-5 is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent input channels capable of detecting under-voltage, over-voltage, and negative voltage conditions with high accuracy. The device operates within a supply voltage range of 2.0V to 6.0V and draws a typical quiescent current of 10µA, ensuring minimal power consumption during standby modes. It provides an open-drain reset output that asserts low when any monitored voltage exceeds its threshold. The component is housed in an 8-lead DFN package suitable for surface-mount applications.

Supervisors Feature Summary

• Monitors up to three independent voltage inputs simultaneously for fault detection
• Provides precise threshold comparison for under-voltage and over-voltage conditions
• Features low quiescent current consumption for battery-powered efficiency
• Delivers a standardized open-drain reset signal upon fault occurrence

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Industrial control systems needing reliable voltage monitoring
• Embedded computing platforms with complex power distribution networks

Supervisors Procurement Notes

Verify the specific suffix IDDB-5 against official datasheets to confirm pinout compatibility and threshold specifications. Ensure the source document explicitly lists this part number as active or available. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and operating temperature ranges before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage lines is required within a compact footprint. Consider the 10µA quiescent current for power-sensitive designs. Verify that the open-drain output interface matches the system's logic requirements. Evaluate the DFN package size constraints against available PCB real estate.
