LM3722IM5X-3.08/NOPB

Supervisors Overview

The LM3722IM5X-3.08/NOPB is a single-channel processor supervisor manufactured by Texas Instruments, housed in a five-pin SOT-23 surface-mount package. It features a fixed voltage threshold of 3.08V for monitoring power supply integrity. The device provides an active-low reset output with an open-drain configuration to ensure compatibility with various logic families. Designed for reliable operation across an industrial temperature range from -40°C to +125°C, it includes a minimum reset timeout of 140ms to allow systems sufficient time to stabilize before asserting the reset signal.

Supervisors Feature Summary

• Provides active-low reset signaling via an open-drain output pin
• Monitors a single power rail against a fixed 3.08V threshold
• Ensures system stability with a guaranteed minimum reset delay

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Digital logic circuit reset management
• Portable electronic device power monitoring

Supervisors Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging when sourcing components. Confirm that the 3.08V threshold aligns precisely with the target supply voltage requirements. Ensure the open-drain output interface matches the pull-up resistor configuration of the connected processor. Check current availability status as manufacturing lifecycles may affect long-term supply continuity.

Supervisors Selection Notes

Select this component when a fixed 3.08V monitoring point is required for low-voltage digital systems. The open-drain output allows flexibility in selecting the pull-up voltage level independent of the monitored rail. Consider the 140ms minimum timeout duration to ensure it exceeds the maximum startup time of the target application. Verify that the SOT-23-5 footprint fits within the available board space constraints.

Supervisors Part Context

This part belongs to the LM3722 family of simple reset circuits designed for cost-sensitive applications. It serves as a fundamental building block for ensuring deterministic system initialization. The device complements other Texas Instruments power management solutions by providing dedicated voltage supervision without requiring external timing components.

Supervisors Replacement Considerations

The LM3722IM5-3.08/NOPB is a non-reel variant of the same electrical specification. Cross-reference with LM3724 series devices if active-high outputs or different timeout characteristics are needed. Verify pinout compatibility before substituting with generic supervisor ICs.
