LM3722IM5X-4.63/NOPB

Supervisors Overview

The LM3722IM5X-4.63/NOPB is a single-channel voltage supervisor manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It features a fixed output threshold of 4.63V and provides a push-pull/totem pole active-low reset signal. The device includes a minimum reset timeout of 100ms to ensure stable power-up sequencing. It operates within a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Provides active-low reset assertion when input voltage drops below the specified threshold.
• Features a built-in reset timeout circuit to guarantee proper power-on reset duration.

Supervisors Applications

• Microprocessor system monitoring
• Battery-powered equipment supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix 'X' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the 4.63V threshold matches the target application requirements. Confirm that the SOT-23-5 footprint aligns with the PCB layout constraints. Check for any recent lifecycle notifications regarding obsolescence or replacement recommendations from Texas Instruments.

Supervisors Selection Notes

Select this component when a fixed 4.63V supervision level is required for low-voltage systems. The SOT-23-5 package offers space efficiency for compact designs. Consider the 100ms minimum timeout for applications requiring extended stabilization periods during power transitions. Evaluate thermal performance within the specified operating temperature range.

Supervisors Part Context

This part belongs to the LM3722 family of simple reset circuits designed for monitoring single voltage rails. It complements other Texas Instruments PMIC solutions by providing essential protection against undervoltage conditions without requiring external components for basic operation.

Supervisors Replacement Considerations
