LTC2913CDD-2#PBF

Supervisors Overview

The LTC2913CDD-2#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring dual voltage rails. It operates within a supply voltage range of 2.7V to 5.5V and features adjustable under-voltage and over-voltage thresholds. The device provides an open-drain reset output with a typical delay of 200ms. It is housed in an 8-lead DFN package, suitable for surface-mount applications across an industrial temperature range.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for independent power rails
• Adjustable threshold detection for under-voltage and over-voltage conditions
• Open-drain reset output with configurable delay timing

Supervisors Applications

• Portable electronic devices requiring dual power domain supervision
• Embedded systems with separate logic and analog power supplies
• Industrial control boards needing robust fault detection

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm threshold configurations and package variations. Ensure compatibility with target PCB footprint dimensions and thermal requirements. Cross-reference the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions prior to finalizing procurement specifications.

Supervisors Selection Notes

Select this component when dual-rail supervision is required in space-constrained designs. Evaluate the adjustable threshold flexibility against system voltage tolerances. Consider the low quiescent current for battery-operated applications. Confirm that the open-drain output interface aligns with the downstream controller's input requirements and pull-up resistor configuration.

Supervisors Part Context

This part belongs to the LTC2913 series of supervisory circuits, which are optimized for monitoring multiple voltage lines in compact packages. The series supports various threshold options and packaging styles to accommodate diverse design constraints. It complements other Analog Devices PMIC solutions by providing reliable fault detection without complex communication interfaces.

Supervisors Replacement Considerations

LTC2913CDD-1#PBF: Offers similar functionality with potentially different fixed threshold settings; verify pinout and electrical parameters match the original design requirements before substitution.
