LTC2933CGN#TRPBF

Supervisors Overview

The LTC2933CGN#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 a guaranteed threshold accuracy of ±1%. The device operates within a supply voltage range of 3.4V to 13.9V and includes two general-purpose inputs and three general-purpose inputs/outputs. It supports supply voltage power sharing from V1 to V4 and offers programmable output delays. The component is housed in a 16-pin SSOP package.

Supervisors Feature Summary

• Simultaneously supervises up to six power supply voltage inputs with I2C-adjustable UV and OV trip points
• Internal EEPROM configuration supports autonomous operation without additional software
• Configurable general-purpose inputs and outputs for manual reset, alert, or fault signaling
• Status and history registers log faults accessible via the I2C interface

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 ordering. Confirm the CGN designation corresponds to the commercial temperature grade and SSOP-16 package variant. Ensure compatibility with I2C/SMBus bus protocols used in the target system design before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when monitoring multiple rails requires precise, field-programmable thresholds rather than fixed hardware values. The internal EEPROM allows for post-manufacturing adjustments to UV/OV settings. Consider the 16-pin SSOP footprint constraints and the need for I2C connectivity on the PCB layout during the initial design phase.

Supervisors Part Context

This part belongs to the LTC2933 family of hex voltage supervisors. It shares functional similarities with other multi-channel monitors but distinguishes itself through EEPROM-based configurability. The CGN#TRPBF variant specifically denotes the commercial grade version packaged in a 16-lead SSOP format for surface-mount assembly.

Supervisors FAQ

Can the UV and OV thresholds be changed after manufacturing?

Yes, the thresholds are I2C-programmable and stored in internal EEPROM, allowing configuration changes without external software support.

What is the guaranteed accuracy of the voltage detection?

The device guarantees a threshold accuracy of ±1% for its overvoltage and undervoltage detection circuits.
