LTC1728ES5-2.5#TRPBF

Supervisors Overview

The LTC1728ES5-2.5#TRPBF is a triple supply monitor manufactured by Analog Devices Inc., designed for systems requiring multiple voltage supervision. It features three independent open-drain outputs for individual power monitoring, with fixed thresholds of 3.086V and 2.338V, and one adjustable channel. The device operates within a temperature range of -40°C to +85°C and is housed in a TSOT-23-5 package. It includes a minimum reset timeout of 140ms and provides active-low reset signals.

Supervisors Feature Summary

• Triple supply monitoring capability with dedicated open-drain outputs for each channel
• Active-low reset signal generation with configurable timeout
• Integrated adjustable voltage threshold alongside fixed reference channels

Supervisors Applications

• Supervision of multiple power rails in embedded systems
• Processor supervisor circuits requiring distinct voltage thresholds
• Automotive electronic control units with multi-voltage architectures

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level specifications to maintain package integrity and electrical performance reliability during assembly processes.

Supervisors Selection Notes

Select this component when precise supervision of three distinct voltage levels is required within a compact surface-mount footprint. The combination of fixed and adjustable thresholds offers flexibility for complex power sequencing requirements without necessitating external resistor networks for the primary rails.

Supervisors Part Context

This part belongs to the LTC1728 series of triple supply monitors from Analog Devices. It complements other supervisory ICs by providing integrated fault detection and reset generation in a minimal package size, suitable for space-constrained applications requiring high reliability across industrial temperature ranges.

Supervisors Replacement Considerations

LTC1728ES5-1.8#TRPBF serves as a direct substitute variant within the same family, differing primarily in the specific voltage threshold configuration while maintaining identical pinout and functional characteristics.
