LTC2919IMS-2.5#TRPBF

Supervisors Overview

The LTC2919IMS-2.5#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent input channels capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device utilizes an open-drain output configuration to signal fault states. It operates within a supply voltage range up to 6 V and maintains high accuracy with a threshold tolerance of 1.5%. The component is housed in a compact MSOP-10 surface-mount package and supports a reset delay time of 200 ms. It functions reliably across an industrial temperature range from -40°C to +85°C while consuming a low quiescent current of 50 µA.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct voltage inputs for comprehensive power rail supervision.
• Detects critical power anomalies including under-voltage, over-voltage, and negative voltage events.
• Delivers precise fault indication through an open-drain output interface compatible with various logic levels.

Supervisors Applications

• Multi-rail power management systems requiring precise voltage supervision
• Industrial control units needing reliable under-voltage and over-voltage protection
• Embedded systems monitoring negative voltage conditions on specific rails

Supervisors Procurement Notes

Verify the exact suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm the IMS variant meets the required -40°C to +85°C operating temperature range for your specific application environment. Ensure the 2.5 V fixed threshold aligns with your system's voltage monitoring requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when three-channel voltage monitoring is required in a small form factor. The MSOP-10 package suits space-constrained designs. The fixed 2.5 V threshold simplifies design if that level matches the monitored rail. Consider the 50 µA quiescent current for battery-sensitive applications. Verify compatibility with the open-drain output requirement of the downstream logic.

Supervisors Part Context

This part belongs to the LTC2919 family of precision voltage monitors from Analog Devices. The family includes variants with different packages such as DFN and CMS, and options for adjustable thresholds or different fixed voltages. The IMS designation specifically indicates the MSOP-10 package style. This series is engineered for applications demanding high accuracy and low power consumption in multi-supply environments.

Supervisors Replacement Considerations

Check for other LTC2919 variants with the same MSOP-10 package but different threshold voltages if the 2.5 V setting is not suitable. Verify pinout compatibility with alternative suppliers' triple-input supervisors. Ensure any substitute supports the required 6 V maximum supply voltage and open-drain output type.
