LTC2903CS6-A1#TRMPBF

Supervisors Overview

The LTC2903CS6-A1#TRMPBF is a precision supervisory circuit manufactured by Analog Devices Inc. It integrates four independent voltage monitors within a compact 6-lead TSOT-23 package. The device features an active-low reset output configured as open drain or open collector, ensuring reliable system protection across multiple power rails.

Supervisors Feature Summary

• Integrates four independent voltage monitoring channels for comprehensive power rail supervision
• Provides precise threshold detection capabilities to ensure accurate system status indication
• Features an active-low reset output with open-drain or open-collector configuration

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• System reset generation for microprocessors and FPGAs
• Voltage supervision in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix A1 against your design requirements, as it denotes a particular threshold variant within the LTC2903 family. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the TSOT-23-6 footprint matches your PCB layout constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of four distinct voltage lines within a minimal footprint. The open-drain reset output allows for flexible wiring-OR configurations with other supervisors. Consider the precision requirements of your application to ensure the fixed thresholds meet your system's safety margins.

Supervisors Part Context

This part belongs to the LTC2903 series of multi-channel supervisors from Analog Devices. It shares the same package and general functionality with variants like the CS6-D1 and IS6-C1, differing primarily in internal threshold settings. The series is designed for applications needing compact, high-precision power management solutions.

Supervisors Replacement Considerations

Direct substitutes include other LTC2903 variants such as LTC2903CS6-D1#TRPBF or LTC2903IS6-C1#TRMPBF, provided their specific threshold voltages align with your design needs. Verify that any replacement maintains the TSOT-23-6 package and open-drain reset output characteristics.
