LTC2919HDDB-5#TRMPBF

Supervisors Overview

The LTC2919HDDB-5#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It features an automotive-grade operating temperature range of -40°C to +125°C and utilizes a 10-pin DFN package with exposed pad. The device monitors under-voltage, over-voltage, and negative voltage conditions with open-drain outputs. It provides a low-active reset signal with a minimum timeout of 140ms. The component operates within a supply voltage range of 1.7V to 6V and consumes a maximum quiescent current of 30µA.

Supervisors Feature Summary

• Supports monitoring of three independent inputs for under-voltage, over-voltage, and negative voltage detection
• Provides a low-active reset output with configurable timeout delay
• Features open-drain output structure compatible with various logic levels
• Designed for automotive applications with extended industrial temperature rating

Supervisors Applications

• Automotive power system supervision
• Multi-rail voltage monitoring in embedded systems
• Negative voltage protection circuits
• Industrial control board supervisor design

Supervisors Procurement Notes

Verify the suffix #WTRMPBF against #TRMPBF as source data indicates potential packaging or reel variations for this family. Confirm the specific threshold configuration matches the '5' designation in the part number. Ensure the automotive grade (H) and 10-DFN package are correctly identified for the target application environment. Cross-reference the manufacturer's latest datasheet for any recent PCN updates regarding bond wire changes.

Supervisors Selection Notes

Select this component when precise monitoring of multiple rails including negative voltages is required in harsh environments. The wide temperature range suits automotive use cases better than commercial variants. Consider the open-drain output requirement for pull-up resistor integration. Evaluate the 140ms reset timeout against system startup requirements. Compare against single-channel monitors if fewer inputs are sufficient to reduce BOM complexity.

Supervisors Part Context

This part belongs to the LTC2919 series of precision voltage monitors from Analog Devices. It shares functional similarities with the LTC2912 and LTC2915 but offers distinct multi-input capabilities. The 'HDDB' code specifies the 10-DFN package and automotive grade, while the '#TRMPBF' indicates tape and reel packaging with lead-free finish. It complements the broader PMIC portfolio for comprehensive power management solutions.

Supervisors Replacement Considerations

LTC2919CDDB-5#TRPBF is listed as a parameter-equivalent alternative in public records. Verify if the commercial grade (C) meets the thermal requirements if the automotive grade (H) is unavailable. Check if the tray packaging (#TRPBF) aligns with assembly line specifications compared to the reel format.
