LM3711XQMM-308/NOPB

Supervisors Overview

The LM3711XQMM-308/NOPB is a microprocessor supervisory circuit manufactured by Texas Instruments. It features a single channel with a threshold voltage of 3.08 V and an active low, open-drain output type. The device includes a manual reset input and a watchdog timer function. It operates within a supply voltage range up to 5.5 V and maintains an accuracy of 0.5%. The reset delay time is specified at 200 ms. The component is housed in a 10-VSSOP package and supports surface mount installation. It functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Provides manual reset capability via dedicated input
• Features active low open-drain output configuration

Supervisors Applications

• Microprocessor power fail detection
• Battery backup switching circuits
• Automotive electronic control units

Supervisors Procurement Notes

Verify the specific suffix '308' confirms the 3.08 V threshold voltage requirement for your design. Ensure the VSSOP-10 package dimensions match your PCB footprint constraints. Confirm that the open-drain output type aligns with your downstream logic interface requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. The 3.08 V threshold suits applications monitoring 3.3 V logic rails. The automotive-grade temperature range makes it suitable for harsh environments. Consider the open-drain output if external pull-up resistors are already present in the target circuit design.

Supervisors Part Context

This part belongs to the LM3710/LM3711 family of microprocessor supervisory circuits. These devices are designed to monitor voltage levels and provide reset signals to protect sensitive electronics. The LM3711 variant specifically offers an open-drain output, distinguishing it from push-pull alternatives in the same series.

Supervisors Replacement Considerations

The LM3710XQMM-308/NOPB is a related variant within the same family. Verify if the output stage difference (open-drain vs. push-pull) impacts the specific application circuit compatibility before substituting.
