LTC2916HDDB-1#TRPBF

Supervisors Overview

The LTC2916HDDB-1#TRPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features nine selectable threshold voltages for precise monitoring. The device provides an open-drain output with a fixed reset delay time of 200 ms and supports manual reset functionality. It lacks a watchdog timer and battery backup switch. The component is housed in an 8-lead DFN package, suitable for surface mount installation. It maintains an accuracy of 1.5% and draws a typical operating supply current of 30 uA. The unit functions reliably across a temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides nine selectable voltage thresholds for flexible power rail monitoring configurations.
• Features a manual reset input allowing external control over the reset state generation.
• Delivers an open-drain output signal compatible with various logic families.
• Ensures high precision monitoring with 1.5% accuracy across the specified operating temperature range.

Supervisors Applications

• Monitoring critical voltage rails in embedded systems requiring manual intervention.
• Power management circuits in industrial automation equipment.
• Supervisory logic in portable instrumentation devices.
• System reset generation in consumer electronics with strict thermal requirements.

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the HDDB variant corresponds to the 8-lead DFN package dimensions. Ensure compatibility with the required 5.5 V maximum supply voltage and 200 ms reset delay for your system design. Check RoHS compliance documentation for environmental regulations. Validate that the manual reset feature aligns with your hardware architecture needs.

Supervisors Selection Notes

Select this component when nine distinct voltage thresholds are necessary for accurate supervision. Consider the 30 uA quiescent current for low-power applications. The manual reset capability distinguishes it from auto-reset variants. Verify the DFN-8 package fits your PCB layout constraints. Ensure the 200 ms delay meets your system startup timing requirements without additional external components.

Supervisors Part Context

This part belongs to the LTC2916 series of voltage supervisors from Analog Devices. It shares the core family architecture but differs in package type and specific threshold selection options compared to other suffixes. The HDDB designation specifies the physical footprint and pin configuration. It complements other PMIC solutions by offering precise monitoring with minimal external component count.

Supervisors Replacement Considerations

LTC2915CDDB-1#TRMPBF offers similar supervision with different threshold options and reset timing characteristics. Evaluate the reset delay differences and threshold availability before substitution. Package compatibility must be verified as both use DFN form factors. Functional equivalence requires checking the manual reset support and output drive capabilities against the original design specifications.
