LTC2933IDHD#PBF

Supervisors Overview

The LTC2933IDHD#PBF is a hex programmable voltage supervisor and reset controller manufactured by Analog Devices Inc. It features six independent monitoring channels with selectable thresholds, housed in a 16-lead DFN package. The device supports manual or automatic reset generation with a timeout of approximately 205 ms. It operates within a supply voltage range of 3.4 V to 13.9 V and functions across an industrial temperature range of -40°C to +85°C. Key specifications include open-drain output types and integrated EEPROM for non-volatile threshold storage.

Supervisors Feature Summary

• Hex programmable voltage monitoring with configurable thresholds
• Integrated EEPROM for persistent configuration storage
• Manual and automatic reset control capabilities
• Wide operating supply voltage range

Supervisors Applications

• Multi-rail power system supervision
• Industrial equipment reset control

• Automotive electronics protection

Supervisors Procurement Notes

Verify the specific suffix and package variant against official Analog Devices documentation to ensure compatibility with design requirements. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference pinout and electrical characteristics with the latest datasheet before integration into production systems.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring and reset management. The integrated EEPROM allows for flexible threshold programming without external components. Ensure the supply voltage range covers all monitored rails and that the output type matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the LTC2933 family of supervisory circuits designed for complex multi-voltage environments. It consolidates multiple monitor functions into a single IC, reducing board space and component count compared to discrete solutions. The DFN package offers thermal efficiency and compact footprint suitable for dense PCB layouts.

Supervisors Replacement Considerations

LTC2933IGN#PBF is a documented alternative offering similar functionality in an SSOP package. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit and electrical integrity in existing designs.
