LM3722IM5-3.08/NOPB

Supervisors Overview

The LM3722IM5-3.08/NOPB is a single-channel voltage supervisor manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It features a fixed threshold voltage of 3.08V and provides an active-low open-drain reset output. The device includes a minimum reset delay time of 1ms to ensure stable power-up sequencing. It operates within a supply voltage range up to 5.5V and supports an industrial temperature range from -40°C to 85°C.

Supervisors Feature Summary

• Provides reliable system reset via active-low open-drain output when monitored voltage drops below the specified threshold.
• Incorporates a guaranteed minimum reset delay time to prevent premature reset assertions during power transitions.
• Designed for low-power applications with minimal supply current consumption.

Supervisors Applications

• Microcontroller and processor power supply monitoring
• Battery-powered portable electronic devices
• Industrial control systems requiring voltage supervision

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the 3.08V threshold aligns precisely with the target circuit requirements. Ensure compatibility with the intended operating temperature range and check for any recent product change notifications regarding pinout or electrical specifications.

Supervisors Selection Notes

Select this component when a fixed 3.08V threshold is required for single-supervision tasks. Compare the 1ms reset delay against system timing constraints to ensure adequate stabilization time. Evaluate the open-drain output capability for necessary pull-up resistor integration. Consider the SOT-23-5 footprint constraints relative to available board space and thermal management needs.

Supervisors Part Context

This part belongs to the LM3722 family of simple reset circuits designed for cost-sensitive and space-constrained applications. It serves as a fundamental building block for power management architectures where voltage integrity is critical. The NOPB designation indicates lead-free construction compliant with RoHS standards, suitable for modern manufacturing environments.

Supervisors Replacement Considerations

Direct substitutes include other LM3722 variants with different threshold voltages if the 3.08V level is adjustable in the design. Cross-reference with LP3470 series parts for similar functionality, noting potential differences in reset delay times and output drive capabilities. Verify pin-to-pin compatibility before swapping to avoid PCB redesign.
