• Power sequencing for field-programmable gate arrays (FPGAs)
• Complex system-on-chip (SoC) power delivery networks

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the IGN suffix corresponds to the industrial temperature grade (-40°C to +85°C) and SSOP package type required for your design. Ensure compatibility with the DC948A evaluation board if initial prototyping is planned.

Power Supply Controllers, Monitors Selection Notes

Select this component when precise control over power-up and power-down sequences is critical for system stability. It is suitable for designs requiring monitoring of multiple rails with customizable thresholds. Consider the I2C interface requirements and available address space when integrating into the system architecture.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2926 family of power supervisors. It is distinct from simple reset controllers as it offers advanced sequencing and tracking features. The device is designed to replace discrete logic solutions, reducing board space and complexity in power management applications.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include other parts within the LTC2926 family with different package options or temperature grades, such as the LTC2926CUFD#PBF. Verify pinout and functional compatibility before replacing.
