LTC2933IGN#TRPBF

Supervisors Overview

The LTC2933IGN#TRPBF is an EEPROM-configurable voltage supervisor designed to simultaneously monitor up to six power supply voltage inputs. It features I2C-programmable over/undervoltage thresholds with guaranteed threshold accuracy of ±1%. The device supports two general-purpose inputs and three general-purpose inputs/outputs, which can be configured for various functions including manual reset or alert outputs. It operates within a supply voltage range of 3.4V to 13.9V and includes internal EEPROM for autonomous configuration without additional software.

Supervisors Feature Summary

• Simultaneously supervises up to six power supply voltage inputs with I2C-adjustable UV and OV trip points
• Internal EEPROM stores configuration parameters to support autonomous operation without external software
• Configurable general-purpose inputs and outputs allow mapping for manual reset, alerts, or auxiliary comparator functions

Supervisors Applications

• High availability computer systems
• Network servers
• Telecom equipment
• Data storage systems

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the 'I' temperature grade matches your environmental requirements. Ensure the SSOP-16 package footprint aligns with your PCB design. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit parts. Check for any recent product change notices regarding pinout or electrical specifications.

Supervisors Selection Notes

Select this component when multi-channel voltage monitoring with programmable thresholds is required. The I2C interface allows flexible configuration of trip points and output polarities. Consider the ±1% threshold accuracy for precise supervision needs. The internal EEPROM simplifies system design by removing the need for external configuration memory. Evaluate the supply voltage range against your system's power rails.

Supervisors Part Context

This part belongs to the LTC2933 family of hex voltage supervisors from Analog Devices. It is distinct from the LTC2934, which offers different pin counts and features. The IGN suffix denotes the industrial temperature grade and SSOP-16 package. The TRPBF suffix specifies the tape and reel packaging format for automated assembly.
