Modern electronic devices require a wide variety of components to ensure an optimal performance. Among the most important components are power management integrated circuits (PMICs), specifically supervisors, which are used to control and manage the power supply of the device. One example of a supervisor PMIC is the BU4911FVE-TR from ROHM Semiconductor. This PMIC provides reliable protection and accuracy for electronic systems and is used for many applications.

The main application of the BU4911FVE-TR is for power reset of digital devices, such as PCs and servers, as well as audio/video systems and networking products. This PMIC is capable of providing an accurate power supply reset, ensuring smooth and safe operation of the device. Aside from reset, the device also provides various types of protection, such as over-voltage protection, over-current protection, and surge protection, which prevents damage to the connected device in the event of an irregular voltage or current.

In terms of features, the BU4911FVE-TR supports a wide range of supply voltages, from 4V to 24V, and is able to monitor and detect irregularities in the voltage quickly and accurately. This PMIC also has a reset output delay of up to 25ms, which allows for a delayed reset operation when needed. In addition, this device has a VDD power-down detection, which monitors the power supply voltage, and will issue a reset if the voltage drops below a certain level.

The working principle of the BU4911FVE-TR is quite simple. This PMIC continuously monitors the voltage level at its input, and if any irregularity is sensed, an output reset signal is generated. This reset signal can trigger the controlled devices to reset, taking them back to the original operating state. In addition, the device also has a built-in timer, which allows for time-delayed reset, allowing the reset process to take place at a pre-determined time period.

Clearly, the BU4911FVE-TR is a valuable and reliable PMIC supervisor for digital devices, allowing for reliable and accurate power management. This device can detect irregularities in the supply voltage quickly, and is capable of providing reset signals with a delay if needed. Furthermore, the various protection features of this PMIC ensures that connected devices remain safe from damage. This makes it a great choice for those looking for an effective and reliable supervisor PMIC for their electronics.
