The MB3793-34DPNF-G-JN-ERE1 is a power management integrated circuit (PMIC) that falls under the category of supervisors. It is mainly used in combination with other electronic components, such as microcontrollers, to ensure the safe operation of electronic systems. This article will discuss the MB3793-34DPNF-G-JN-ERE1’s application field and working principle.

Application Field:

The MB3793-34DPNF-G-JN-ERE1 supervisor is used in a variety of fields, such as automotive, industrial, consumer, and medical applications. It is suitable for applications where reliability, safety, and power consumption are of great importance. In automotive applications, the MB3793-34DPNF-G-JN-ERE1 supervisor can be used to monitor and protect power subsystems from overloads and short circuits. It can also be used to monitor and protect communication networks from short circuits and voltage surges. Additionally, the MB3793-34DPNF-G-JN-ERE1 supervisor can be used in industrial applications such as automated equipment, PLC controllers, and process automation systems. In consumer applications, the MB3793-34DPNF-G-JN-ERE1 supervisor can be used in digital cameras, MP3 players, and other portable electronic devices. Finally, in medical applications, the MB3793-34DPNF-G-JN-ERE1 supervisor can be used in medical imaging systems and medical pumps.

Working Principle:

The MB3793-34DPNF-G-JN-ERE1 supervisor is a three-channel voltage monitor that monitors a system’s input power supply. It includes a precision voltage reference, a comparator, and a logic circuit. The precision voltage reference provides a reference voltage to the comparator. The comparator compares the input voltage with the reference voltage to detect any voltage changes. If the voltage changes, the comparator sends a logic signal out to the logic circuit. The logic circuit then sends a reset signal to the system if the input voltage falls outside of the preset range. The reset signal is used to protect the system from potential damage caused by voltage irregularities.

The MB3793-34DPNF-G-JN-ERE1 supervisor also includes a power-on reset circuitry. This circuitry automatically resets the system when the power supply is turned on. Additionally, the MB3793-34DPNF-G-JN-ERE1 supervisor includes a current mirror circuit, which monitors the current consumption of the system. The current mirror circuit sends out an over-current signal if the system’s current consumption exceeds the preset level, which can be used to protect the system from short circuits and overloads.

The MB3793-34DPNF-G-JN-ERE1 supervisor also includes a watchdog timer. The watchdog timer monitors the system’s activities and sends out a reset signal if the system fails to respond within the predetermined time limit. This reset signal helps to prevent the system from crashing due to system faults or malfunctions.

Finally, the MB3793-34DPNF-G-JN-ERE1 supervisor includes a clock monitor, which monitors the system’s clock signals and sends out a reset signal if any of the clock signals fail. This reset signal helps to protect the system from data loss due to timing errors.

In summary, the MB3793-34DPNF-G-JN-ERE1 supervisor is a PMIC that is used in many different fields, including automotive, industrial, consumer, and medical applications. Its main function is to monitor and protect power subsystems, communication networks, and other electronic components from potential damage due to voltage irregularities, over-currents, and timing errors. It includes a variety of components, such as a precision voltage reference, a comparator, a logic circuit, a power-on reset circuitry, a current mirror circuit, a watchdog timer, and a clock monitor.
