LMC6953CM

Supervisors Overview

The LMC6953CM is a dual-channel power supply supervisor designed for PCI Local Bus applications. It monitors two voltage inputs with threshold voltages of 2.65 V and 4.4 V. The device features an active low, open-drain output and supports manual reset functionality. It operates within a supply voltage range up to 6 V and functions between 0°C and +70°C. Packaged in an 8-SOIC surface-mount case, this component provides essential monitoring for system integrity.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for critical power rails
• Active low open-drain output interface for flexible logic integration
• Manual reset input allows for controlled system recovery

Supervisors Applications

• PCI Local Bus power supervision
• Multi-voltage system monitoring
• Embedded controller power management

Supervisors Procurement Notes

Verify the obsolete status of the LMC6953CM before procurement planning. Confirm availability of exact substitutes or alternative components from Texas Instruments. Ensure that any replacement part matches the original electrical specifications and package dimensions to maintain system compatibility without redesign.

Supervisors Selection Notes

Select this component only if dual-channel supervision with specific 2.65 V and 4.4 V thresholds is required. Consider the 8-SOIC package constraints and the active low output polarity. Evaluate whether manual reset meets the design requirements compared to automatic watchdog options available in newer generations.

Supervisors Part Context

This device belongs to the LMC6953 series of supervisory circuits from Texas Instruments. It is specifically engineered for PCI Local Bus environments where precise voltage tracking is necessary. The series focuses on providing reliable monitoring solutions for legacy and industrial systems requiring stable power supervision.

Supervisors Replacement Considerations

Check for LMC6953CMX/NOPB as a potential variant. Verify exact pinout and threshold compatibility with any third-party equivalents. Ensure the substitute maintains the open-drain output structure and SOIC-8 footprint.
