LTC2911HDDB-2#TRMPBF

Supervisors Overview

The LTC2911HDDB-2#TRMPBF is a multi-voltage supervisor integrated circuit manufactured by Analog Devices Inc. It features three independent monitoring channels housed in an 8-lead DFN package. The device provides push-pull/totem pole outputs with active-low reset signals and adjustable or selectable reset timeouts. It operates within a temperature range of -40°C to 85°C TA.

Supervisors Feature Summary

• Monitors up to three distinct power supply voltages simultaneously
• Provides active-low reset output with configurable timeout periods
• Utilizes a compact surface-mount DFN package for space-constrained designs

Supervisors Applications

• Multi-rail embedded system power supervision
• Industrial control board voltage monitoring
• Portable instrumentation power integrity verification

Supervisors Procurement Notes

Verify the specific suffix 'HDDB-2' against official Analog Devices documentation to confirm threshold configurations. Ensure the DFN-8 package footprint matches the PCB layout requirements. Confirm RoHS3 compliance status through the manufacturer's current material declaration before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltage rails is required. Compare the fixed thresholds associated with the '-2' suffix against design requirements. Evaluate the push-pull output capability versus open-drain alternatives if noise immunity or drive strength is critical for the application logic interface.

Supervisors Part Context

This part belongs to the LTC2911 family of supervisory circuits designed for reliable power management. It serves as a specialized variant within Analog Devices' portfolio, offering multi-channel oversight in a small form factor suitable for modern electronic assemblies requiring robust fault detection capabilities.

Supervisors Replacement Considerations

LTC2911HDDB-1#TRMPBF: Different voltage threshold configuration. LTC2911ITS8-1#TRMPBF: Different TSOT-23-8 package type.
