LTC2903IS6-C1#TRMPBF

Supervisors Overview

The LTC2903IS6-C1#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in compact systems. It features four independent input channels capable of detecting under-voltage and over-voltage conditions to ensure system integrity. The device operates within a supply voltage range of 2.5V to 5.5V and draws a typical quiescent current of 20µA, making it suitable for power-sensitive applications. It provides an active-low reset output with a fixed delay time of 200ms to prevent false triggering during transient events. The component is housed in a space-saving TSOT-23-6 package, facilitating integration into dense printed circuit board layouts.

Supervisors Feature Summary

• Four-channel voltage supervision for comprehensive power rail monitoring

Supervisors Procurement Notes

Verify the specific suffix C1 against official Analog Devices documentation to confirm the exact threshold voltage configuration before procurement. Ensure the TSOT-23-6 footprint matches your PCB design constraints. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate that the operating temperature range meets your environmental specifications.

Supervisors Selection Notes

Select this component when designing systems that require simultaneous monitoring of four distinct voltage levels within a limited board area. Consider the 200ms reset delay duration to ensure compatibility with your microcontroller's startup sequence. Evaluate the 20µA quiescent current impact on overall battery life if used in portable applications. Verify that the input voltage range aligns with the specific rails being monitored. Assess the thermal performance requirements given the small package size.
