LM3723EM5-3.08

Supervisors Overview

The LM3723EM5-3.08 is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single power supply rails. It operates within an extended 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 3.08V and provides an active-low reset signal with an open-drain configuration. A minimum reset timeout of 100ms ensures stable system recovery during power transitions.

Supervisors Feature Summary

• Provides reliable processor reset generation through manual reset functionality
• Features low quiescent current consumption for battery-powered applications
• Includes internal hysteresis to prevent false triggering from noise

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Battery-operated portable devices requiring power supervision
• Industrial control systems operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering. Confirm that the 3.08V threshold aligns with the target supply rail requirements. Check for any recent product change notifications regarding manufacturing sites or marking revisions to ensure compatibility with existing assembly processes.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a precise 3.08V threshold is required. Ensure the open-drain output capability matches the pull-up resistor configuration in the design. Consider the SOT-23-5 footprint constraints and verify thermal performance within the specified -40°C to +125°C operating range for the intended environment.

Supervisors Part Context

This part belongs to the LM372x series of simple reset circuits from Texas Instruments. It shares architectural similarities with the LM3722 and LM3724 models but differs in specific threshold voltages and feature sets. The series is widely used in general-purpose power management applications where cost-effective voltage supervision is necessary.

Supervisors Replacement Considerations

Direct substitutes include other variants within the LM372x family, such as the LM3722 or LM3724, provided the threshold voltage matches the application requirement. Verify pinout compatibility and electrical specifications before swapping components.
