LTC2916CDDB-1#TRMPBF

Supervisors Overview

The LTC2916CDDB-1#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides a reset signal with nine selectable threshold options. The device features an open-drain output, manual reset capability, and a fixed 200 ms reset delay time. It operates within a supply voltage range of up to 5.5 V and maintains an accuracy of 1.5%. The component functions reliably across an industrial temperature range from -40°C to +125°C, drawing a typical quiescent current of 30 µA. It is housed in an 8-pin DFN package.

Supervisors Feature Summary

• Provides manual reset functionality for controlled system recovery
• Offers nine selectable voltage threshold options for flexible monitoring
• Features low power consumption suitable for battery-operated applications

Supervisors Applications

• Monitoring power rails in embedded systems requiring manual intervention
• Industrial control units operating in extended temperature environments
• Portable electronic devices utilizing low-power voltage supervision

Supervisors Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging when ordering. Confirm the CDDB variant meets the required industrial temperature specifications compared to other grade variants. Ensure the manual reset pin configuration aligns with the target board design. Cross-reference the nine selectable thresholds against the application voltage requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset is required. The nine selectable thresholds provide flexibility without external resistors. The wide operating temperature range suits harsh environments. Compare the 200 ms delay against system startup timing needs. Consider the open-drain output compatibility with the target logic levels.

Supervisors Part Context

This part belongs to the LTC2916 series of voltage supervisors. It shares functional similarities with the LTC2915 but differs in package and threshold selection. The DFN-8 package offers a compact footprint for space-constrained designs. It complements other PMIC components in complex power management architectures.

Supervisors Replacement Considerations

LTC2916HDDB-1#TRPBF serves as a direct replacement with identical electrical characteristics but utilizes high-temperature grading and different packaging quantities.
