MN13811-S

Supervisors Overview

The Panasonic MN13811-S is a CMOS LSI voltage detector designed for monitoring single power supply rails. It functions as a simple reset or power-on reset circuit, ensuring system stability by detecting under-voltage conditions. The component operates within a wide input voltage range and provides a reliable output signal to microcontrollers or logic circuits when the monitored voltage drops below a specific threshold. It is housed in a compact package suitable for space-constrained PCB layouts.

Supervisors Feature Summary

• Monitors a single power supply voltage level for system integrity
• Generates reset signals upon detection of under-voltage events
• CMOS technology ensures low power consumption during operation

Supervisors Applications

• Microcontroller power-on reset circuits
• Battery-powered device supervision
• Embedded system voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix designation (e.g., -S) against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the component status is active for new designs, as older revisions may be obsolete. Cross-reference the specific voltage threshold requirements with the application needs before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor is required for CMOS-based systems. Consider the operating temperature range and package size constraints relative to the target PCB design. Verify that the reset delay time meets the timing requirements of the connected logic devices to prevent false triggering during power-up sequences.

Supervisors Part Context

This part belongs to the MN13811 series of CMOS LSI voltage detectors manufactured by Panasonic Industrial Devices. The series includes variants with different voltage thresholds and package options, such as the MN13811SN and MN13811SL. These components are engineered for reliability in consumer electronics and industrial control applications requiring precise voltage supervision.

Supervisors Replacement Considerations

Check for direct substitutes within the MN13811 family, such as the MN13811SN or MN13811SL, which may offer compatible pinouts or similar electrical characteristics. Ensure any replacement maintains the same voltage monitoring threshold and reset functionality to avoid redesigning the surrounding circuitry.
