The BU4935FVE-TR is a type of power management integrated circuit (PMIC) found in a range of applications. The name Supervisors, or voltage supervisors, is one of the categories of PMICs, and it applies to the BU4935FVE-TR. Supervisors are used to monitor the power supply of a device, and this article will look at its application field, working principle and structure.

Application Field of BU4935FVE-TR

The BU4935FVE-TR is a PMIC found in a range of fields, including consumer electronics, automotive, industrial and medical applications. It is ideal for detecting low current main power supply problems in these applications.

For example, in consumer electronics, the BU4935FVE-TR supervisor is often used to detect voltage drops due to a dead battery, power supply interruptions caused by a power outage or surge, and thermal issues caused by over usage.

In automotive applications, the supervisor can detect voltage drops or power supply interruptions caused by engine or transmission failures, or when a car is parked for a long time. This can lead to issues with other vehicle components as well as a reduction in reliability.

In industrial applications, voltage drops caused by power supply problems can lead to downtime in a factory or other industrial environment. The BU4935FVE-TR supervisor can detect these problems before they cause an issue, and can even reset the power supply if needed.

Finally, in medical applications, the BU4935FVE-TR supervisor can detect voltage drops or power supply interruptions caused by faulty or delicate parts. This can help to prevent medical device malfunctions and improve the reliability of the equipment.

Working Principle of BU4935FVE-TR

The working principle of the BU4935FVE-TR supervisor is to monitor the power supply. It has an internal voltage detector that continuously monitors the power supply and can detect low voltage or other abnormal situations.

When the voltage drops below a certain threshold, the supervisor will enter into monitoring mode and will alert the user of the problem. It can then reset the power supply if needed, and if the problem persists, it will shut down the power supply to protect the device.

The supervisor can also be used to monitor for overvoltage problems, and can alert the user when the power supply exceeds a certain threshold. This can help to prevent damaging the device or the components in it.

The BU4935FVE-TR supervisor also has a watchdog timer feature that can be used to detect and alert the user of system malfunctions or errors. The watchdog timer is reset each time the user intervenes, and if it is not reset within a certain period, it will alert the user of an issue.

Structure of BU4935FVE-TR

The BU4935FVE-TR supervisor is a type of power management integrated circuit with a built in voltage detector. It is composed of a P-channel MOSFET, an N-channel MOSFET, a comparator, a voltage reference, a resistor divider, a voltage detector and a watchdog timer.

The P-channel MOSFET is used to control the power supply, and the N-channel MOSFET is used to reset the power supply when needed. The voltage reference and the resistor divider are used to create a reference voltage for the comparator, which is then used to detect the power supply voltage.

The voltage detector is used to detect low voltage or other abnormal voltages, and the watchdog timer is used to detect system malfunctions or errors. The whole supervisor is integrated into a single IC, making it an ideal choice for use in various applications.

Conclusion

The BU4935FVE-TR is a type of power management integrated circuit found in a wide range of applications. It belongs to the Supervisors category of PMICs, and is used to monitor the power supply of a device. The application field, working principle and structure of the BU4935FVE-TR have been examined in this article, and it can be seen that it is an ideal choice for detecting power supply issues in various applications.
