UCD9080RHBR

Supervisors Overview

The UCD9080RHBR is a voltage supervisory circuit manufactured by Texas Instruments, designed for power supply sequencing and monitoring applications. It features eight monitored inputs and digital outputs within a VQFN-32 package. The device operates with a maximum supply voltage of 3.6 V and a minimum of 3 V, drawing 4.5 mA of operating current. It supports programmable reset delay times and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides sequential power-up and power-down control for multiple rails
• Monitors up to eight independent voltage inputs simultaneously
• Features programmable reset delay timing for customized sequencing
• Delivers digital output signals for system supervision

Supervisors Applications

• Multi-rail server power distribution units
• Industrial equipment power management systems
• Telecommunications infrastructure power supplies
• Embedded computing board power sequencing

Supervisors Procurement Notes

Verify the specific suffix RHBR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal performance for the intended operating environment. Cross-reference the datasheet for exact pinout configurations to prevent PCB layout errors during assembly.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of eight distinct voltage rails. The VQFN-32 package offers a compact footprint suitable for space-constrained layouts. Consider the programmable reset delays to align with specific load ramp-up requirements. Verify that the 3V to 3.6V supply range aligns with the controller logic levels in the target design.

Supervisors Part Context

This part belongs to the UCD9080 series of power supply sequencers and monitors. It serves as a specialized PMIC solution for managing complex power states in electronic systems. The device integrates supervision logic to ensure stable operation during power transitions. It complements other Texas Instruments power management components in comprehensive system designs.

Supervisors Replacement Considerations

The UCD9080RHBT is a compatible alternative offering identical electrical specifications but packaged in cut-tape format instead of reel. Both variants share the same functional capabilities and pinout configuration. Verify package compatibility before substituting to ensure mechanical fit on the printed circuit board.
