LM3722IM5-2.32/NOPB

Supervisors Overview

The LM3722IM5-2.32/NOPB is a single-channel processor supervisor manufactured by Texas Instruments, designed to monitor voltage levels in electronic systems. It features a fixed output threshold of 2.32V and provides a reset signal with active-low polarity. The device utilizes a push-pull/totem pole output configuration and includes a minimum reset timeout of 100ms to ensure system stability during power transitions. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality for monitored circuits
• Features an active-low output signal with push-pull drive capability
• Includes a guaranteed minimum reset timeout duration for reliable operation

Supervisors Applications

• Monitoring supply voltages in embedded microprocessor systems
• Ensuring stable power-up sequences in portable electronic devices
• Providing reset signals for digital logic circuits requiring voltage supervision

Supervisors Procurement Notes

Verify the specific suffix '2.32' confirms the 2.32V threshold voltage, as the LM3722 family offers multiple threshold options. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Check current availability status as this component may be subject to lifecycle changes or obsolescence notices from the manufacturer.

Supervisors Selection Notes

Select this part when a fixed 2.32V monitoring threshold is required for low-voltage applications. The push-pull output allows direct driving of logic inputs without external pull-up resistors. Consider the SOT-23-5 package size for space-constrained designs. Ensure the operating temperature range meets the environmental requirements of the target application.
