LTC2919HMS-2.5#TRPBF

Supervisors Overview

The LTC2919HMS-2.5#TRPBF is a precision voltage monitor from Analog Devices, featuring three independent monitoring channels housed in a 10-lead MSOP package. It supports dual input configurations for under-voltage and over-voltage detection, as well as negative voltage monitoring. The device operates with a supply voltage range of 2.7V to 6V and draws a typical quiescent current of 50µA. It provides an open-drain reset output with a fixed 200ms delay. The threshold voltage is factory-set at 2.5V, ensuring high accuracy within the specified industrial temperature range.

Supervisors Feature Summary

• Provides precise monitoring for under-voltage, over-voltage, and negative voltage conditions across multiple inputs
• Features a low-power architecture suitable for battery-operated systems with minimal quiescent current consumption
• Delivers a reliable open-drain reset signal with a guaranteed minimum delay time to prevent premature system restarts

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems needing robust voltage supervision
• Communication equipment monitoring critical power rails

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the MSOP-10 package variant matches your PCB footprint requirements. Ensure the 2.5V threshold aligns with your system's voltage levels. Check for RoHS compliance documentation relevant to your region. Validate availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when multi-channel supervision is required without manual reset functionality. Compare against adjustable threshold variants if flexible voltage settings are needed. Consider the MSOP-10 package size constraints relative to available board space. Evaluate the 200ms reset delay against system startup timing requirements. Assess the 50µA current draw impact on overall system efficiency.

Supervisors Part Context

This part belongs to the LTC2919 series of precision supervisors designed for monitoring complex power architectures. It complements other Analog Devices PMIC solutions by providing dedicated fault detection capabilities. The series supports various package options including DFN and MSOP formats to accommodate different design densities.

Supervisors Replacement Considerations

Direct substitutes include other parts within the LTC2919 family with adjusted thresholds or packages, such as the LTC2919IMS-2.5#PBF. Verify pin compatibility and electrical specifications before substitution.
