TPS3610T50PWR

Supervisors Overview

The TPS3610T50PWR is a battery-backup supervisor integrated circuit manufactured by Texas Instruments, designed for RAM retention applications. It operates within an input voltage range of 2.0 V to 5.5 V and features a fixed reset threshold voltage of 4.63 V. The device provides a push-pull active-low reset output with a typical delay of 200 ms. It functions reliably across an industrial temperature range from -40°C to +85°C and is housed in a standard SOT-23 surface-mount package.

Supervisors Feature Summary

• Provides automatic backup power switching between main supply and external battery sources
• Generates a system reset signal upon detection of low-voltage conditions
• Includes a manual reset input pin for controlled system initialization

Supervisors Applications

• Non-volatile memory retention circuits
• Embedded systems requiring brown-out protection
• Portable electronic devices with dual power sources

Supervisors Procurement Notes

Verify the specific suffix 'PWR' indicates the tape-and-reel packaging variant when ordering. Confirm that the 4.63 V threshold aligns with the target memory retention voltage requirements. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain performance specifications.

Supervisors Selection Notes

Select this component when a fixed 4.63 V supervision threshold is required for RAM or EEPROM retention. It is suitable for designs needing a simple, low-pin-count solution for power monitoring. Consider alternative models if adjustable thresholds or higher voltage ranges are necessary for the application.

Supervisors Part Context

This part belongs to the TPS3610 family of battery-backup supervisors. It shares functional similarities with other members like the TPS3610U18 but differs in its fixed reset threshold voltage. The family is engineered specifically for maintaining data integrity in volatile memory during power transitions.

Supervisors Replacement Considerations

The TPS3610T50PW is the equivalent tube-packaged version of this component. Other variants within the TPS3610 series may serve as substitutes if their specific threshold voltages match the design requirements.
