LTC2919CMS-5#TRPBF

Supervisors Overview

The LTC2919CMS-5#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features three independent inputs capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device operates within a supply voltage range up to 6 V and maintains an accuracy of 1.5%. It utilizes an open-drain output configuration with a reset delay time of 200 ms. The component is housed in a compact MSOP-10 package and functions reliably across a temperature range from 0°C to +70°C.

Supervisors Feature Summary

• Provides simultaneous monitoring for three distinct input channels including negative voltage detection
• Delivers high measurement accuracy with a specified tolerance of 1.5 percent
• Features an open-drain output interface suitable for direct logic integration

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Monitoring negative voltage rails in mixed-signal circuits
• Over-voltage and under-voltage protection in industrial control units

Supervisors Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm the -5 variant matches the required threshold specifications against the official datasheet. Ensure the MSOP-10 footprint aligns with the target PCB layout. Check current availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when precise monitoring of three separate voltage lines is required. The fixed threshold version simplifies design compared to adjustable variants. Consider the 200 ms reset delay for system timing requirements. Verify that the open-drain output capability meets the downstream logic interface needs.

Supervisors Part Context

This part belongs to the LTC2919 series of precision voltage monitors. It shares core functionality with other variants in the family but differs in package type and threshold configuration. The CMS designation indicates the MSOP-10 surface-mount package. The -5 suffix specifies the fixed threshold voltage setting for the monitored inputs.
