LTC1728ES5-1.8#TRMPBF

Supervisors Overview

The LTC1728ES5-1.8#TRMPBF 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 thresholds set at 1.683V, 2.805V, and an adjustable level. The device provides active-low reset signals with a minimum reset timeout of 140ms. It operates within a temperature range of -40°C to 85°C and is housed in a TSOT-23-5 package.

Supervisors Feature Summary

• Triple channel monitoring with dedicated open-drain outputs for independent supply supervision
• Active-low reset signal generation with defined timeout characteristics
• Integrated threshold configuration including fixed and adjustable voltage monitoring points

Supervisors Applications

• Supervision of multiple power rails in complex electronic systems
• Processor supervisor circuits requiring distinct voltage monitoring channels
• Systems utilizing DC/DC feedback dividers for precise voltage tracking

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm package integrity and pin alignment against the TSOT-23-5 specification. Ensure thermal management aligns with the specified operating temperature range during integration. Cross-reference datasheet revisions to validate electrical parameters before final design approval.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required within a compact footprint. The adjustable threshold option allows flexibility for non-standard rail voltages. Consider the open-drain output configuration compatibility with downstream logic interfaces. Evaluate the reset timeout duration against system startup requirements to ensure reliable initialization sequences.

Supervisors Part Context

This part belongs to the LTC1727/LTC1728 family of triple supply monitors from Analog Devices. It shares functional similarities with other members of the series but offers specific threshold configurations tailored for multi-voltage applications.
