LM3712XQBP-308/NOPB

Supervisors Overview

The LM3712XQBP-308/NOPB is a microprocessor supervisory circuit from Texas Instruments designed for system stability monitoring. It features a single monitored input with a threshold voltage of 3.08 V. The device provides an active low reset output via a push-pull, totem pole configuration. Key timing specifications include a minimum reset timeout of 140 ms. It operates within a temperature range of -40°C to +85°C and is housed in a 9-USMD package.

Supervisors Feature Summary

• Monitors system voltage stability with a dedicated threshold setting
• Provides active low reset signal through push-pull output stage
• Includes integrated watchdog timer functionality for fault detection

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset management
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the 'BP' package code corresponds to the 9-USMD footprint required by your PCB layout. Ensure the '308' designation matches the 3.08 V threshold requirement for your target rail. Cross-reference the datasheet revision date to confirm electrical characteristics have not changed in newer releases.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a precise 3.08 V threshold is required. The push-pull output allows direct driving of logic inputs without external pull-ups. Consider the 140 ms minimum timeout for systems requiring longer initialization periods. The wide operating temperature range suits industrial environments. Verify that the 9-USMD package fits within the available board space constraints.

Supervisors Part Context

This part belongs to the LM371x series of microprocessor supervisory circuits. It complements other variants like the LM3710 and LM3712 in different packages. The series focuses on providing reliable reset signals for digital systems. It serves as a critical component for ensuring proper boot sequences and protecting against brown-out conditions in embedded applications.

Supervisors Replacement Considerations

Check for LM3712XQBP-308 without NOPB if lead-free status is not critical. Verify pinout compatibility with existing designs before substituting. Ensure alternative parts support the same 3.08 V threshold and 140 ms timeout requirements.
