LTC2903IS6-E1#TRPBF

Supervisors Overview

The LTC2903IS6-E1#TRPBF is a quad supply monitor from Analog Devices, designed for precision voltage supervision in compact systems. It features four independent window comparators with adjustable thresholds, housed in a 6-lead TSOT-23 package. The device operates within a temperature range of -40°C to +85°C and draws a typical quiescent current of 20 µA. It provides a reset output to signal out-of-range conditions, ensuring reliable system protection in space-constrained applications requiring multi-voltage monitoring.

Supervisors Feature Summary

• Four independent window comparators provide precise monitoring of multiple supply rails simultaneously
• Adjustable threshold voltages allow customization for specific application requirements
• Compact 6-lead TSOT-23 packaging facilitates integration into space-constrained designs
• Low quiescent current consumption supports battery-powered and energy-efficient systems

Supervisors Applications

• Multi-rail power supply monitoring in industrial equipment
• Voltage supervision in portable consumer electronics
• System reset generation in embedded computing platforms
• Battery management systems requiring precise voltage tracking

Supervisors Procurement Notes

Verify the exact suffix E1 against your design specifications, as it denotes specific electrical characteristics or testing criteria defined by Analog Devices. Confirm availability through authorized distributors, as supply status may vary. Ensure the TSOT-23-6 footprint matches your PCB layout. Cross-reference the datasheet for thermal performance and operating conditions relevant to your environment.

Supervisors Selection Notes

Select this component when four independent voltage monitors are required in a minimal footprint. Compare quiescent current and threshold accuracy against alternatives if power efficiency or precision is critical. Verify that the adjustable threshold range covers all monitored rails. Consider the reset output polarity and delay characteristics relative to your system's timing requirements.

Supervisors Part Context

This part belongs to the LTC2903 series of quad supply monitors from Analog Devices. The series offers flexible configuration options for supervising multiple voltages. Variants like the CS6 and IS6 differ in temperature ranges and initial accuracy, while suffixes such as E1 indicate specific production revisions or testing standards. The TSOT-23-6 package is common across the family for compact implementations.

Supervisors Replacement Considerations

Direct substitutes include other LTC2903 variants with compatible pinouts, such as LTC2903CS6-C1#TRPBF or LTC2903IS6-C1#TRMPBF, provided their temperature ranges and accuracy meet your design needs. Verify that any replacement maintains the same quad-monitor functionality and package dimensions.
