LTC2933IGN#PBF

Supervisors Overview

The LTC2933IGN#PBF is an EEPROM-configurable voltage supervisor designed to monitor up to six power supply inputs simultaneously. It features I2C-programmable overvoltage and undervoltage thresholds with guaranteed accuracy. The device includes two general-purpose inputs and three general-purpose I/Os for flexible system control. It supports a supply voltage range of 3.4V to 13.9V and offers programmable output delays and fault logging via status registers.

Supervisors Feature Summary

• Simultaneous supervision of six independent power supply voltages
• I2C/SMBus interface for programmable threshold configuration
• Internal EEPROM retains configuration for autonomous operation
• Configurable general-purpose inputs and outputs

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix IGN#PBF against the manufacturer datasheet to confirm package type (SSOP-16) and temperature range (-40°C to 85°C). Ensure compatibility with existing I2C bus configurations and voltage levels. Cross-reference part numbers carefully as suffixes indicate distinct packaging and operational parameters.

Supervisors Selection Notes

Select this component when multi-rail monitoring is required with precise, software-adjustable thresholds. The internal EEPROM allows field reconfiguration without external memory. Consider the SSOP-16 package constraints and I2C addressability when designing the PCB layout and firmware architecture for complex power management topologies.

Supervisors Part Context

This part belongs to the LTC2933 family of hex voltage supervisors from Analog Devices. It is specifically the industrial temperature grade version in a 16-pin SSOP package. The family provides scalable power monitoring solutions for systems requiring detailed fault detection and recovery logic across multiple power domains.

Supervisors Replacement Considerations

LTC2933CGN#PBF: Same functionality in DFN-16 package. LTC2933IGN#TRPBF: Tape and reel packaging variant.
