MB3793-30PNF-G-JN-EF-6E1

Supervisors Overview

The MB3793-30PNF-G-JN-EF6E1 is a voltage monitor supervisory circuit manufactured by Infineon Technologies. It operates within a supply voltage range of 1.2 V to 6 V and features a threshold voltage of 3 V with an overvoltage threshold of 3.14 V. The device provides a CMOS output type and includes a watchdog timer functionality. It has a reset delay time of 75 ms and consumes a working power supply current of 31 uA. The component is housed in an SSOP-8 package, supports surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides CMOS logic output interface
• Supports single-input voltage monitoring

Supervisors Applications

• Embedded system voltage supervision
• Microcontroller reset circuitry
• Portable electronic device power management

Supervisors Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as EF6E1 may indicate specific packaging or tape-and-reel configurations. Confirm availability status as the product lifecycle is listed as obsolete. Ensure compatibility with SSOP-8 footprint requirements during procurement planning.

Supervisors Selection Notes

Select this component when a low-power voltage monitor with integrated watchdog functionality is required. The 3 V threshold suits applications monitoring 3.3 V or similar logic rails. Consider the SSOP-8 package size constraints and the 31 uA quiescent current impact on battery life. Verify that the 75 ms reset delay meets the target system's startup timing requirements.

Supervisors Part Context

This part belongs to Infineon's supervisory circuits portfolio, specifically designed for power management ICs. It serves as a critical component for ensuring stable operation in digital systems by detecting under-voltage conditions and managing system resets through its dedicated watchdog feature.

Supervisors Replacement Considerations

As the product status is listed as obsolete, verify if newer generations from the same family or compatible third-party equivalents are available. Check pinout compatibility and electrical parameter alignment before substitution.
