TPS3707-25DG4

Supervisors Overview

The TPS3707-25DG4 is a dual-input voltage supervisory circuit manufactured by Texas Instruments, designed for processor systems requiring precise power monitoring. It operates within a supply voltage range of up to 6 V and features an adjustable threshold voltage of 2.41 V. The device provides active high and active low push-pull outputs with a fixed reset delay time of 200 ms. Packaged in an MSOP-PowerPAD-8 surface-mount format, it supports manual reset functionality without integrated watchdog timers or battery backup switches. Operating temperatures span from -40°C to +85°C, ensuring reliability in industrial environments.

Supervisors Feature Summary

• Dual-input voltage supervision with adjustable threshold detection
• Active high and active low push-pull output configurations
• Manual reset capability for system control flexibility

Supervisors Applications

• TMS320C6000 DSP reset circuits
• Multi-supply voltage monitoring in embedded processors
• Power-fail detection in industrial control systems

Supervisors Procurement Notes

Verify the specific suffix DG4 indicates lead-free RoHS compliance and confirm package type matches MSOP-PowerPAD-8. Check current lifecycle status as some TPS3707 variants face obsolescence. Ensure design-in documentation references the correct 2.41 V threshold variant rather than generic family parameters.

Supervisors Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision before processor release. The adjustable threshold allows customization for non-standard rail voltages. Verify that the 200 ms delay meets system startup timing requirements and that manual reset integration fits the board layout constraints.

Supervisors Part Context

Part of the TPS370x family of processor supervisory circuits offering multi-rail monitoring. Distinguished by its dual-input architecture compared to single-channel supervisors. The DG4 suffix denotes environmental compliance. Designed specifically for complex digital signal processors requiring coordinated power sequencing validation.

Supervisors Replacement Considerations

TPS3707-25DRG4 offers identical electrical specifications in SOIC-8 packaging. TPS3705 series provides similar functionality but may differ in input count or package options. Verify pinout compatibility and threshold accuracy before substitution.
