LTC1728ES5-5#TRMPBF

Supervisors Overview

The LTC1728ES5-5#TRMPBF is a triple power-supply monitor manufactured by Analog Devices Inc., housed in a TSOT-23-5 surface-mount package. It monitors three voltage rails with fixed thresholds of 4.63V, 2.805V, and 1.683V. The device features an active-low open-drain reset output and a minimum reset timeout of 140ms. Operating from -40°C to +85°C, it supports input voltages up to 16V and draws minimal quiescent current.

Supervisors Feature Summary

• Monitors three independent voltage rails simultaneously
• Provides active-low open-drain reset signal
• Includes guaranteed minimum reset timeout duration

Supervisors Applications

• Portable equipment power management
• Battery-powered systems supervision
• Embedded controller power sequencing

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Confirm availability through authorized distributors as supply status may vary. Ensure the fixed threshold configuration matches the design requirements before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required within a compact footprint. The fixed thresholds eliminate external resistor programming complexity. Verify that the 140ms minimum reset timeout aligns with system startup timing constraints and that the open-drain output interface is compatible with the target logic family.

Supervisors Part Context

This part belongs to the LTC1728 series of triple power-supply monitors. It shares the TSOT-23-5 package and core architecture with variants featuring different threshold combinations or adjustable references. The ES5 designation indicates the specific temperature range and package style offered by Analog Devices for industrial applications.

Supervisors Replacement Considerations

LTC1728ES5-1.8#TRMPBF is a direct substitute offering identical functionality but with different monitored voltage thresholds.
