LTC2909ITS8-5#TRMPBF

Supervisors Overview

The LTC2909ITS8-5#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 6V and features three independent monitoring channels with open-drain outputs. The device includes an adjustable reset delay timer, selectable thresholds for under-voltage, over-voltage, and negative voltage detection, and manual reset functionality. It is housed in an 8-pin TSOT-23 package.

Supervisors Feature Summary

• Provides precise monitoring for up to three independent voltage inputs including under-voltage, over-voltage, and negative voltage conditions
• Features manual reset capability allowing system control over the reset state
• Includes an adjustable reset delay timer to prevent false triggering during power transitions

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-powered systems needing under-voltage protection
• Industrial control circuits with multiple voltage rails

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain device integrity upon installation.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision with manual reset is required in space-constrained designs. The TSOT-23 package offers a compact footprint suitable for portable applications. Consider the adjustable reset delay feature for noise immunity in sensitive environments.

Supervisors Part Context

This part belongs to the LTC2909 series of precision voltage monitors from Analog Devices. The series is designed for applications requiring accurate supervision of multiple voltage rails with minimal quiescent current consumption. It complements other PMIC solutions by providing dedicated supervisory functions in a small form factor.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the same family such as LTC2909 variants with different threshold configurations. Verify functional equivalence regarding reset delay adjustability and output drive capabilities before substitution.
