BUK220-50Y,118 application field and working principle

The BUK220-50Y,118 belongs to a family of power management integrated circuits (PMIC) known as Power Distribution Switches, Load Drivers. It is used to keep microprocessors and other integrated circuits safe from damage due to voltage spikes, surges, or overloads. Voltage surges, in particular, put integrated circuits at risk because they can cause both overvoltage and undervoltage conditions on the supply line. The BUK220-50Y,118 is designed to protect vulnerable circuits from these voltage spikes by providing an effective power supply management network.

The BUK220-50Y,118 is a high-side MOSFET half-bridge driver intended to be used in a wide range of applications that require high-side switching from an external logic signal. It is composed of two main components, an output driver and two MOSFETs. The output driver contains a voltage controller and a scheduler block. The voltage controller is responsible for driving the MOSFETs with the desired voltage accuracy, while the scheduler block is responsible for initiating the switching control of the MOSFETs.

The BUK220-50Y,118 has two main functions. First, it is capable of providing an efficient supply management solution. This is achieved by providing a reliable overcurrent/overvoltage protection feature, along with programmable current regulation. This helps to ensure that the power output is steady and reliable, while also preventing any damage due to overload or surge protection. Secondly, the BUK220-50Y,118 provides a high-side MOSFET driver that precisely controls the switching between “on” and “off” states for high-side switching of the MOSFETs. This feature enables its use in a range of applications such as power supplies and motor drivers.

The BUK220-50Y,118 is a versatile, efficient and reliable power supply management IC. Its integrated power management system provides both overvoltage and overcurrent protection while its accurate voltage regulation helps to ensure steady and reliable power output. Its high-side switching feature ensures precise control of the MOSFETs, making it useful for a wide range of applications.
