LTC1728ES5-2.5#TRMPBF

Supervisors Overview

The LTC1728ES5-2.5#TRMPBF is a triple voltage supervisor IC manufactured by Analog Devices Inc., housed in a TSOT-23-5 surface-mount package. It monitors three distinct voltage rails, featuring fixed thresholds for two channels and an adjustable threshold for the third. The device provides active-low reset outputs with open-drain or open-collector configurations to ensure system integrity during power fluctuations.

Supervisors Feature Summary

• Triple-channel voltage monitoring capability with configurable thresholds
• Active-low reset signal generation with specified timeout duration
• Open-drain or open-collector output interface for flexible logic integration

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Microcontroller reset circuitry requiring multiple voltage checks
• Industrial control units needing reliable power failure detection

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Ensure the part number matches the exact threshold specifications required for your design, as variations exist within the LTC1728 family. Cross-reference with authorized distributors to confirm current availability and authenticity.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltage levels is required in a compact footprint. The adjustable channel allows customization for non-standard rail voltages. Confirm that the open-drain output compatibility matches the downstream logic requirements and that the reset timeout meets the system startup timing constraints.

Supervisors Part Context

This part belongs to the LTC1728 series of triple supervisors, designed for applications requiring comprehensive power management oversight. It complements other PMIC solutions by providing dedicated hardware-based reset signals without software intervention, ensuring robust operation in safety-critical environments.

Supervisors Replacement Considerations

Direct substitutes include other parts from the LTC1728 family with matching pinouts and threshold configurations. Verify electrical parameters such as operating temperature range and quiescent current before substitution to maintain system performance.
