LM3722EM5-2.32/NOPB

Supervisors Overview

The LM3722EM5-2.32/NOPB is a single-channel voltage supervisor manufactured by Texas Instruments, designed to monitor power supply integrity in electronic systems. It operates within an extended industrial temperature range of -40°C to +125°C and utilizes a compact SOT-23-5 surface-mount package. The device features a fixed output threshold of 2.32V, ensuring precise detection of under-voltage conditions. It provides a push-pull/totem pole output configuration with a minimum reset timeout of 100ms, facilitating reliable microprocessor reset generation without requiring external components.

Supervisors Feature Summary

• Integrated simple reset and power-on reset functionality for automated system recovery
• Fixed 2.32V monitoring threshold eliminates the need for external resistor dividers
• Push-pull output stage capable of driving logic interfaces directly

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered devices requiring low-voltage detection
• Industrial control units operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix EM5 against the requested IM5 variant to ensure correct temperature grade alignment. Confirm that the 2.32V threshold matches the target application's under-voltage requirements. Check current production status as TI frequently updates component availability and lifecycle notices for legacy supervisory parts.

Supervisors Selection Notes

Select this component when a fixed 2.32V threshold is required for power monitoring. The SOT-23-5 package suits space-constrained designs. Ensure the 100ms minimum reset delay aligns with the target processor's startup timing specifications. Verify compatibility with the system's logic voltage levels given the push-pull output architecture.
