Introduction

The SM72240MFX-4.63/NOPB is a low-power, advanced process Supervisory Microcontroller offered by Texas Instruments. The device is designed as an extended feature supervisor that helps in preventing against unexpected power supply issues. It is specifically designed to optimize system performance, providing integrated circuits with ideal protection against uncontrollable system shutdowns. This makes it ideal for applications with high reliability requirements.

Application Field

The SM72240MFX-4.63/NOPB is a suitable supervisors for applications that require a high level of protection from unexpected power supply events such as brownouts, overvoltage and undershoot of supplied power. It is designed for reliable systems that need a focal point for safety and system integrity. The device is suitable for applications such as unattended security systems, industrial computers, servers and robot monitoring systems. The benefit of using the device is that it can provide the user with the peace of mind that the system will continue to operate without interruption.

Working Principle

The SM72240MFX-4.63/NOPB works on the concept of detecting at a minimum two different power supply conditions. It also has the capability to detect more than one power supply conditions when integrated with multiple power supplies.

The first stage of the supervisor is the power-on-reset (POR). Through this stage, the supervisor will actively search for the power supply before it canproceed to the next stage. During this stage, the device initiates a logic to ensure current through the device remains constant even when there is a power supply issue. This allows the device to provide uninterrupted power supply.

The second stage of the supervisor is the fault detection stage. This is where the device acts as a supervisor to watch for any faults or failures in the system. During this stage, the supervisor can detect conditions such as an overvoltage, undershoot of supplied power, or a fault. The device then automatically triggers a pin active state to alert the system of any issues.

The third stage of the supervisor is the power control stage. During this stage, the supervisor will set the power level required in the system. It can also be used to control power to reduce power consumption, resulting in an overall increase in system efficiency. The device also offers different operational modes for controlling the system’s power level and can be configured to tailor to various power supply requirements.

Conclusion

The SM72240MFX-4.63/NOPB is a reliable and low-power advanced process Supervisory Microcontroller from Texas Instruments. It has been designed for applications with high reliability requirements, offering protection from unexpected power supply issues. The device offers an optimized safeguard for system performance, working in three stages to detect and monitor power levels to ensure a safe and continuous operation of the system.
