LTC2903IS6-D1#TRMPBF

Supervisors Overview

The LTC2903IS6-D1#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., housed in a TSOT-23-6 surface-mount package. It functions as a quad voltage monitor with an active-low reset output, designed to track four independent input voltages. The device operates within a supply voltage range of 1.25V to 5.5V and features a quiescent current of 20µA. It supports configurable thresholds for under-voltage and over-voltage detection, ensuring reliable system monitoring in compact electronic designs.

Supervisors Feature Summary

• Monitors four independent voltage rails simultaneously
• Provides active-low reset signal upon threshold violation
• Configurable threshold settings for flexible application
• Low power consumption suitable for battery-operated systems

Supervisors Applications

• Portable electronics requiring multi-rail supervision
• Industrial control systems with multiple power domains
• Communication equipment needing voltage integrity checks
• Automotive infotainment and instrumentation modules

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm threshold configurations. Ensure the TSOT-23-6 package matches your PCB footprint requirements. Check availability status as distribution channels may report limited stock or end-of-life conditions. Confirm RoHS compliance and lead times with authorized distributors prior to ordering.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage lines is required in a minimal footprint. Consider the 20µA quiescent current for energy efficiency constraints. Verify that the input voltage ranges align with your system's power rails. The TSOT-23-6 package offers space-saving advantages for dense layouts compared to larger packages.

Supervisors Part Context

This part belongs to the LTC2903 series of supervisory circuits from Analog Devices. It shares functional similarities with other quad monitors but differs in package type and specific threshold configurations defined by the suffix. The series is designed for applications demanding high reliability and low power usage in portable and industrial environments.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LTC2903 family, such as variants with different suffixes indicating threshold adjustments. Cross-reference with other quad supervisors from Analog Devices if specific timing characteristics differ. Ensure any substitute maintains the TSOT-23-6 package and electrical specifications.
