LM3722IM5X-2.32/NOPB

Supervisors Overview

The LM3722IM5X-2.32/NOPB is a single-channel voltage supervisor integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.62 V to 5.5 V and features a fixed reset threshold voltage of 2.32 V. The device utilizes an SOT-23-5 surface-mount package and provides a push-pull output configuration. It includes manual reset functionality and supports active-low or active-high reset signal selection via external components.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 2.32 V threshold for system protection
• Features manual reset input allowing user-controlled assertion of the reset signal
• Delivers a push-pull output stage compatible with various logic families
• Operates reliably across a wide industrial temperature range

Supervisors Applications

• Portable equipment battery monitoring
• Microcontroller power-on reset circuits
• Battery-powered smart cards
• Watchdog timer supervision

Supervisors Procurement Notes

Verify the specific suffix '2.32' confirms the 2.32 V threshold voltage, as other variants exist in the LM3722 family. Ensure the 'X' designation indicates tape-and-reel packaging if reel handling is required. Confirm the 'NOPB' suffix denotes lead-free and RoHS compliance. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with existing board designs.

Supervisors Selection Notes

Select this component when a fixed 2.32 V supervision level is required for low-voltage systems. Consider the manual reset feature if external control over the reset state is necessary. Evaluate the SOT-23-5 package size constraints against available PCB space. Compare performance requirements such as quiescent current and reset delay times against alternative supervisors in the same family.

Supervisors Part Context

This part belongs to the LM372x series of voltage supervisors from Texas Instruments. The series includes variants with different threshold voltages, such as the LM3722IM5X-3.08/NOPB and LM3722IM5X-4.63/NOPB. These devices share common architectural features but differ primarily in their trip points. The LM3722 specifically targets applications requiring supervision around the 2.32 V level.
