LTC2919IMS-3.3#TRPBF

Supervisors Overview

The LTC2919IMS-3.3#TRPBF is a precision triple/dual input under-voltage and over-voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 6V and features an open-drain output type with a reset delay time of 200 ms. The device monitors three inputs, offering threshold voltages of 2.921V, adjustable settings, and fixed options like 3.3V. It consumes 50 uA of operating power current and maintains an accuracy of 1.5%. Packaged in a 10-MSOP format, it supports surface mount installation and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring for multiple voltage rails including under-voltage and over-voltage conditions
• Features configurable threshold detection capabilities for flexible system integration
• Delivers low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision

Supervisors Procurement Notes

Verify the specific suffix and package variant against your schematic requirements before ordering. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Ensure compatibility with your assembly process regarding the MSOP-10 footprint and reflow soldering profiles specified in the official datasheet.

Supervisors Selection Notes

Select this component when designing circuits that require simultaneous monitoring of three distinct voltage lines with high accuracy. Consider the 1.5% accuracy specification and 200 ms reset delay for timing-sensitive applications. Evaluate the 50 uA supply current against total system power budgets to ensure efficient operation during standby modes.

Supervisors Part Context

This part belongs to the LTC2919 series of supervisory circuits designed for complex power management tasks. It complements other variants in the family such as the CMS and CDDB packages, offering designers flexibility in form factor selection while maintaining consistent electrical performance characteristics across the product line.

Supervisors Replacement Considerations

Direct substitutes include other LTC2919 variants with different package styles or fixed thresholds, such as LTC2919CMS-3.3#TRPBF or LTC2919CDDB-3.3#TRMPBF. Verify pinout compatibility and thermal performance differences between MSOP, TSSOP, and DFN packages before swapping.
