BU4223F-TR

Working Principle

The BU4223F-TR is designed to monitor the power supply voltage of systems and prevent damage or malfunction due to abnormal voltage. In addition, it provides the safety of the system by disconnecting the power supply voltage from the power supply when the voltage exceeds the upper and lower limit values set in advance. The monitoring range is from VCC 0.8V to 8.4V, and the accuracy for the output voltage is 0.0025V/step.

Moreover, the BU4223F-TR provides array of monitoring functions such as Voltage Supervision: The BU4223F-TR is capable of continuously monitoring the power supply voltage, and providing a warning or an alert if the voltage deviates from the set values. It can also override the power supply voltage to the safe levels. Current Limit: The BU4223F-TR provides current-limiting features to detect and limit any excessive current draw that might result in a malfunction or damage.

The BU4223F-TR also provides protection functions such as Overvoltage Protection: This protects the device from voltage fluctuations caused by power supply instability or inadvertent operations by the user. Overcurrent Protection: This feature detects and limits any excessive current draw that might result in a malfunction or damage. Short-Circuit Protection: This protects the device from the accidental short-circuiting of the power supply or any of its connections.

In addition, the BU4223F-TR provides various control functions such as Soft Start: The control of the rise time for power supply output to limit the inrush current. Power-on Reset: This is used to reset the system when the power is turned on. Watchdog Timer: This timer can be used to monitor the status of the device and reset it when necessary.
