UCD90910RGCR

Supervisors Overview

The UCD90910RGCR is a voltage supervisory circuit manufactured by Texas Instruments, designed for system health monitoring and power rail sequencing. It features a VQFN-64 package and supports up to ten monitored inputs with programmable reset delay times. The device operates within a supply voltage range of 3 V to 3.6 V and functions reliably across an industrial temperature range from -40°C to +125°C. With a typical operating supply current of 50 mA, it is suitable for surface mount installation in complex power management applications requiring precise sequence control.

Supervisors Feature Summary

• Supports sequential power-up and power-down of multiple voltage rails
• Provides continuous monitoring of system health and input voltages
• Features configurable reset timing parameters for flexible integration

Supervisors Applications

• Multi-rail server power distribution units
• Industrial controller power sequencing
• Telecommunications infrastructure equipment
• High-density computing board power management

Supervisors Procurement Notes

Verify the specific ordering suffix RGCR to confirm the VQFN-64 package type and reel packaging configuration. Ensure compatibility with the required thermal dissipation characteristics for the target application environment. Confirm that the design accommodates the specified 50 mA operating current draw during active monitoring phases.

Supervisors Selection Notes

Select this component when designing systems requiring dedicated hardware-based sequencing for ten or fewer power rails. Consider the VQFN-64 footprint constraints and the need for programmable reset delays. Evaluate the 3 V to 3.6 V supply requirement against available logic levels and ensure the -40°C to +125°C rating meets environmental specifications.
