LTC2900-1IDD#PBF

Supervisors Overview

The LTC2900-1IDD#PBF is a low-power, high-accuracy programmable quad supply monitoring circuit manufactured by Analog Devices Inc. It features a common reset output and a manual reset input, designed for systems with up to four supply voltages. The device allows selection from 16 preset or adjustable voltage monitor combinations. It operates within an ambient temperature range of -40°C to 85°C and consumes 50 µA of operating supply current. The component is housed in a compact 10-DFN (3x3) surface-mount package.

Supervisors Feature Summary

• Programmable quad supply monitoring capability supporting up to four distinct voltage rails
• Configurable reset timing with adjustable timer functionality
• Open drain or open collector common reset output architecture

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for portable electronic devices
• Industrial control system power integrity verification

Supervisors Procurement Notes

Verify the exact suffix #PBF indicates leaded packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Check current availability status as distribution may vary. Ensure the DFN-10 package matches your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when monitoring four independent supply voltages is required. Consider the 50 µA quiescent current for battery-sensitive designs. Verify that the 10-DFN package fits your assembly constraints. Ensure the manual reset input meets your system's safety requirements.

Supervisors Part Context

This part belongs to the LTC2900 series of supervisory circuits. It serves as a specialized power management IC for complex multi-voltage environments. The series focuses on accuracy and programmability for critical system protection applications.

Supervisors Replacement Considerations

LTC2900-1IMS#TRPBF is a tape-and-reel variant of the same functional device. Verify package compatibility between DFN and MSOP styles if substituting.
