LTC2919HMS-5#PBF

Supervisors Overview

The LTC2919HMS-5#PBF is a precision supervisory circuit from Analog Devices, designed for monitoring multiple voltage rails. It features three independent input channels capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device operates with a maximum supply voltage of 6 V and draws a typical quiescent current of 50 uA. It provides an open-drain output with a fixed reset delay time of 200 ms. Accuracy is specified at 1.5%, and it functions within a temperature range of 0°C to +70°C in a 10-lead MSOP package.

Supervisors Feature Summary

• Supports triple or dual input monitoring for UV, OV, and negative voltage detection
• Includes polarity selection and buffered reference output capabilities
• Features low power consumption with 50 uA operating supply current
• Provides open-drain output with 200 ms reset delay

Supervisors Applications

• System monitoring in portable electronics
• Battery-powered equipment supervision
• Industrial control system voltage tracking
• Communication infrastructure power management

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm the MSOP-10 package availability matches your assembly requirements. Check regional distribution status as some variants may have limited stock. Ensure the 0°C to +70°C commercial temperature range meets your operational environment needs before finalizing procurement.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage lines is required in space-constrained designs. The 1.5% accuracy ensures reliable threshold detection without external calibration. Consider the 50 uA quiescent current for battery life optimization. The open-drain output simplifies interface logic integration. Verify that the 6 V maximum supply voltage aligns with your system's highest rail.

Supervisors Part Context

This part belongs to the LTC2919 series of precision monitors. It shares functional similarities with other members like the LTC2919CMS-5#PBF but differs in package type and industrial/commercial grade specifications. The H-grade variant typically denotes extended temperature ranges or higher reliability standards compared to standard C-grade parts within the same family.

Supervisors Replacement Considerations

Direct substitutes include LTC2919CMS-5#PBF and LTC2919IDDB-5#WTRMPBF. Verify pin compatibility and electrical parameter alignment before substitution. Package differences between MSOP and DFN may require layout adjustments. Ensure threshold voltages match your specific application requirements.
