LM3704XCMMX-263

Supervisors Overview

The LM3704XCMMX-263 is a single-channel microprocessor supervisor integrated circuit manufactured by Texas Instruments. It monitors a single voltage supply with a threshold of 2.63V. The device features a push-pull, totem pole output configuration and provides an active-low reset signal. It includes a minimum reset timeout of 140ms to ensure stable power-up sequences. The component operates within a temperature range of -40°C to +125°C and is housed in a 10-VSSOP surface-mount package.

Supervisors Feature Summary

• Monitors a single voltage rail with a fixed 2.63V threshold
• Provides active-low reset signal with push-pull output drive
• Ensures system stability via a minimum 140ms reset timeout period

Supervisors Applications

• Embedded systems requiring reliable power-on reset sequencing
• Microcontroller unit (MCU) power supply supervision
• Industrial control boards operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix '263' confirms the 2.63V threshold requirement for your design. Confirm the 'X' indicates tape-and-reel packaging if automated assembly is required. Check current product status as some variants may be discontinued or subject to last-time buy notices. Ensure the 10-VSSOP footprint matches your PCB layout constraints.

Supervisors Selection Notes

Select this part when a precise 2.63V monitoring level is necessary for the target logic family. The push-pull output allows direct interfacing with digital inputs without external pull-ups. Consider the 140ms minimum timeout against your system's startup duration requirements. Verify that the 10-pin VSSOP package fits within the available board space and thermal management plan.

Supervisors Part Context

This component belongs to the LM3704 series of simple supervisors designed for basic power management tasks. It serves as a fundamental building block for ensuring processor integrity during power transitions. The series offers various threshold voltages to accommodate different logic levels, with this specific variant targeting lower voltage rails common in modern embedded applications.

Supervisors Replacement Considerations

Check for LM3704XCMMX-263/NOPB which denotes lead-free compliance. Other LM3704 variants with different suffixes offer alternative threshold voltages but require verification of electrical compatibility.
