BTS5014SDA AUMA1 is a low side power distribution switch, load driver, and load current reporting device designed by Infineon. It is qualified for automotive application. The device is a monolithic integrated module that controls and regulates the power supply of automotive system components. The BTS5014SDAAUMA1 offers a low on-resistance at a voltage range up to 40V and a continuous current up to 5.5A. The device also has an active protection characteristic that includes over temperature protection and current protection.

The BTS5014SDAAUMA1 can be used in a wide range of applications, including automotive automation, power distribution, and power monitoring systems. The device is ideal for controlling multiple channels, such as powering headlamps, door lights, driver information displays, and engine control systems. It is also suitable for control of low-side power switches in automotive smart grid systems.

The working principle of the BTS5014SDAAUMA1 is that it uses an integrated power switch in combination with a linear current regulator. The power switch is responsible for creating a stable voltage level and the current regulator ensures that the current supplied by the device is maintained at a regulated level. The power switch and current regulator are both controlled by the integrated control module, which is responsible for providing the necessary control signals and enabling protection.

The BTS5014SDAAUMA1 provides two types of driving mode: single-channel and dual-channel. In single-channel mode, the device drives one output load, while in dual-channel mode, two output loads can be driven simultaneously. The device also features a low input voltage (1.8V) for increased efficiency and a low quiescent current. It has an extended temperature range ranging from -40℃ to +125℃.

The BTS5014SDAAUMA1 contains an integrated protection circuit that provides over-temperature and over-current protection. The device supports multiple protection functions and pin assignments. The integrated protection circuit ensures safe operation in automotive environments.

In summary, the BTS5014SDAAUMA1 is a low side power distribution switch, load driver, and load current reporting device that enables the efficient control of multiple channels in automotive power distribution systems. The device provides two types of driving mode, low input voltage and extended temperature range, along with integrated protection functions to ensure safe operation in automotive environments.
