LM3710XQMM-308/NOPB

Supervisors Overview

The LM3710XQMM-308/NOPB is a microprocessor supervisory circuit manufactured by Texas Instruments. It integrates power fail detection, low line output, manual reset functionality, and a watchdog timer within a single package. The device operates with a supply voltage range of 1.2 V to 5.5 V and features an adjustable reset threshold voltage set at 3.08 V. Designed for automotive applications, it meets AEC-Q100 qualification standards and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates power fail input monitoring with low line output capability
• Includes manual reset control and dedicated watchdog timer outputs
• Supports adjustable reset threshold voltages for flexible system protection

Supervisors Applications

• Automotive microprocessor system supervision
• Embedded controller reset management
• Watchdog timer implementation in vehicle electronics

Supervisors Procurement Notes

Verify the specific suffix '308' corresponds to the 3.08 V threshold setting as documented in official datasheets. Confirm AEC-Q100 automotive grade status through manufacturer certification documents. Ensure compatibility with existing PCB footprints for the VSSOP-8 package before procurement.

Supervisors Selection Notes

Select this component when automotive-grade reliability is required for microprocessor supervision. The integrated watchdog and power fail features reduce external component count. Verify that the 3.08 V threshold aligns with the target system's logic levels and operating voltage requirements.

Supervisors Part Context

This part belongs to the LM3710 family of supervisory circuits designed for robust system monitoring. It serves as a critical interface between power management and processor control in demanding environments. The NOPB suffix indicates lead-free construction compliant with RoHS directives.

Supervisors Replacement Considerations

Publicly confirmed substitutes include the LM3710MM/NOPB and LM3712MM/NOPB. Verify functional equivalence regarding watchdog timer configuration and power fail sensitivity before substitution.
