LTC2911IDDB-4#TRMPBF

Supervisors Overview

The LTC2911IDDB-4#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in power management systems. It operates within a supply voltage range of 2.5V to 36V and features a quiescent current of 850nA. The device provides three monitored channels with fixed thresholds of 3.086V, 4.675V, and an adjustable threshold. It utilizes a push-pull/totem pole output configuration with active-low reset signaling and offers selectable or adjustable reset timeouts. The component is housed in an SOT-23-8 (TSOT-23-8) surface-mount package and supports industrial operating temperatures from -40°C to 85°C.

Supervisors Feature Summary

• Provides simultaneous supervision of three distinct voltage inputs including under-voltage and over-voltage detection capabilities
• Features configurable reset timing with selectable or adjustable timeout periods to accommodate various system startup requirements
• Delivers active-low reset signals through a push-pull output stage for robust interface compatibility with digital logic

Supervisors Applications

• Multi-rail power sequencing in embedded computing platforms
• Industrial control systems requiring reliable voltage supervision
• Telecommunications equipment power management units

Supervisors Procurement Notes

Verify the specific suffix designation to ensure correct threshold configurations and package variants match design requirements. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly planning. Cross-reference datasheet specifications against target application environmental conditions to validate operational reliability across the specified temperature range.

Supervisors Selection Notes

Select this component when multi-channel voltage monitoring is required with low standby current consumption. The adjustable threshold option allows flexibility for custom voltage references. Ensure the SOT-23-8 footprint aligns with PCB layout constraints. Compare performance metrics against alternative supervisors if higher channel counts or different output types are needed.

Supervisors Part Context

This part belongs to the LTC2911 series of precision voltage monitors from Analog Devices. It shares functional similarities with other members like the LTC2912 and LTC2915 but differs in channel count and output structure. The series is characterized by high accuracy and low power consumption suitable for battery-operated and space-constrained applications.

Supervisors Replacement Considerations

Direct substitutes include other Analog Devices parts such as LTC2911ITS8-1#TRMPBF for different threshold configurations. Verify pinout compatibility and electrical parameters before substitution. Alternative manufacturers may offer functionally equivalent devices but require thorough validation of timing and threshold accuracies.
