LTC2911HDDB-5#TRPBF

Supervisors Overview

The LTC2911HDDB-5#TRPBF is a precision triple supply monitor and power-fail comparator manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.6V to 5.5V with a quiescent current of 10µA. The device features three independent voltage monitoring channels with fixed thresholds of 3.086V, 4.675V, and an adjustable threshold. It provides an open-drain reset output and a push-pull power-fail output. The component is housed in an 8-lead DFN package measuring 3mm x 2mm with an exposed pad, suitable for surface-mount applications.

Supervisors Feature Summary

• Integrates three independent voltage monitoring channels with fixed and adjustable thresholds
• Includes a dedicated power-fail comparator with push-pull output capability
• Features low quiescent current consumption for efficient power management
• Provides open-drain reset output with selectable timeout delay

Supervisors Applications

• Portable instrumentation systems requiring multi-voltage supervision
• Industrial automation control boards needing reliable power monitoring
• Embedded systems with multiple logic voltage domains
• Battery-powered devices requiring efficient power management

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the operating temperature range meets application requirements. Check for RoHS compliance status as per manufacturer documentation. Ensure the DFN-8 package dimensions align with PCB layout constraints. Validate that the fixed threshold voltages match system design specifications before procurement.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage rails is required. Consider the adjustable threshold channel for flexible voltage detection needs. Evaluate the low quiescent current benefit for battery-operated designs. Compare the DFN package size against available board space. Assess the need for both reset and power-fail signals in the system architecture.

Supervisors Part Context

This part belongs to the LTC2911 series of precision supply monitors from Analog Devices. It complements other variants like the LTC2911IDDB-1 and LTC2911ITS8-1 which offer different packages or threshold configurations. The HDDB-5 variant specifically utilizes the 8-lead DFN package format common in compact electronic designs.

Supervisors Replacement Considerations

LTC2911HDDB-2#TRPBF offers similar functionality with different threshold settings. LTC2911IDDB-1#TRPBF provides equivalent features in a different package variant. Verify electrical compatibility and pinout alignment before substituting any alternative part numbers.
