LTC2908ITS8-A1#TRPBF

Supervisors Overview

The LTC2908ITS8-A1#TRPBF is a six-input power supply monitor manufactured by Analog Devices Inc. It operates within a voltage range of 2.7V to 26.4V and features a low quiescent current of 50µA. The device provides precise monitoring for multiple supply rails, including fixed thresholds at 4.675V, 3.086V, 2.338V, and 1.683V, alongside two adjustable inputs. It utilizes an open-drain active-low reset output and is housed in an 8-pin TSOT-23 package.

Supervisors Feature Summary

• Six-input architecture supporting simultaneous monitoring of multiple power rails
• Fixed internal threshold voltages combined with configurable adjustable channels
• Low power consumption suitable for battery-operated systems
• Compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Systems requiring precise supervision of multiple distinct voltage levels
• Portable electronic devices needing compact power management solutions
• Industrial equipment monitoring complex multi-rail power architectures
• Embedded systems utilizing mixed voltage logic families

Supervisors Procurement Notes

Verify the specific suffix A1 against official datasheets to confirm the exact threshold configuration matches design requirements. Confirm availability status as distribution channels may indicate restricted supply or limited stock conditions. Ensure the TSOT-23-8 footprint aligns with PCB layout specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing circuits that require monitoring more than four supply voltages within a minimal footprint. Consider the fixed versus adjustable input balance to determine if external resistor networks are necessary for custom thresholds. Evaluate the 50µA quiescent current impact on overall system efficiency during active operation phases.

Supervisors Part Context

This part belongs to the LTC2908 series of supervisory circuits designed for multi-supply monitoring. It complements other Analog Devices PMIC components by providing dedicated voltage tracking without requiring microcontroller intervention. The series supports various package options to accommodate different board density requirements.

Supervisors Replacement Considerations

Direct substitutes include other variants within the LTC2908 family, such as LTC2908CTS8-A1#TRPBF, which share identical functional characteristics but differ in package type. Verify pinout compatibility and threshold configurations before implementing any cross-package replacements.
