The BTS5480SFXUMA1 is a monolithic integrated power switch from Infineon, designed to provide maximum reliability, flexibility, and cost-efficiency.

It is a highly integrated power management IC (PMIC) that is capable of providing superior current and low power solutions. The BTS5480SFXUMA1 is especially suitable for applications that require highly regulated current and power distribution, such as automotive, industrial, and consumer products.

The BTS5480SFXUMA1 is a component of the Power Distribution Switches, Load Drivers, and Load Management and Safety ICs product family. This product family is designed to provide power solutions for applications requiring superior current and power distribution across multiple and varied system components. With the BTS5480SFXUMA1, power is managed and applied in a protected, reliable, and efficient manner. The device can be used to drive multiple loads with a maximum current rating of 5 amps.

The BTS5480SFXUMA1 offers various features to ensure optimal performance and reliability. First, it has an integrated over-temperature and over-current protection to guard against possible system failures. Second, it can be used to establish a switching voltage of up to 100V, enabling it to be used in a wide range of applications. Finally, the device is equipped with an integrated low-noise filtering stage, allowing the user to reduce noise interference from other components in the system.

The working principle of the BTS5480SFXUMA1 is quite simple. The device utilizes an insulated-gate bipolar transistor (IGBT) to switch the power and manage current distribution. The IGBT is powered by a low-voltage input, with two high-side MOSFETs being used to control the logic levels of the IGBT.

The high-side MOSFETs are connected between the input and the IGBT, while a low-side MOSFET is connected between the output and the IGBT. In a steady state, the low-side MOSFET is used to keep the voltage across the IGBT constant, while the high-side MOSFETs control the switching. When it is time to switch the power on or off, the logic levels of the MOSFETs are changed in order to make the IGBT invert or turn off, respectively.

In addition to controlling the current distribution, the BTS5480SFXUMA1 also provides protection from overloading. When an overload occurs, the device senses the excess current and shuts off the circuit to prevent damage. The integrated over-temperature and over-current protection can be used to protect the system from short circuits, overvoltage, and overcurrent. The device also provides a wide ±2V operating voltage range to accommodate different system requirements.

The BTS5480SFXUMA1 from Infineon is one of the latest additions to the Power Distribution Switches, Load Drivers, and Load Management and Safety ICs product family. With its outstanding features, the device is suitable for various applications such as automotive, industrial, and consumer products. With its integrated protection, switching voltage range, and low-noise filtering stages, the BTS5480SFXUMA1 is an ideal choice for power management and switching applications.
