LTC2919HMS-5#TRPBF

Supervisors Overview

The LTC2919HMS-5#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It monitors under-voltage, over-voltage, and negative voltage conditions across three independent channels. The device features an open-drain output and operates within a supply voltage range up to 6V. It provides a reset delay time of 200 ms and maintains an accuracy of 1.5%. The component is housed in a 10-MSOP package and functions within a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Monitors multiple voltage rails for under-voltage, over-voltage, and negative voltage faults
• Provides precise threshold detection with adjustable settings
• Delivers open-drain reset signaling for system supervision

Supervisors Applications

• Multi-rail power supply monitoring in industrial systems
• Battery backup system supervision
• Embedded controller voltage integrity verification

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the MSOP-10 package variant matches the design footprint. Ensure the operating temperature range meets environmental requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required without manual reset functionality. The adjustable thresholds allow customization for specific rail tolerances. Consider the low quiescent current for power-sensitive designs. Verify that the open-drain output interface aligns with the downstream logic levels of the monitored system.

Supervisors Part Context

This part belongs to the LTC2919 series of precision supervisors. It shares functional similarities with variants like the LTC2919CMS-5#PBF but differs in packaging and reel configuration. The series is designed for applications requiring reliable voltage monitoring with high accuracy and low power consumption.

Supervisors Replacement Considerations

LTC2919CDDB-5#TRMPBF is listed as a parameter-equivalent alternative.
