The BU24035GW-E2 is an automotive power motor controller IC intended for use within powertrain related applications, in particular ones that involve the control of rotating machines such as pumps, blowers, fans and motors. It is produced by the German semiconductor manufacturer, Infineon, as part of their Automotive Power Management Integrated Circuit (PMIC) range. The BU24035GW-E2 is capable of providing a total output current capability of at least 5A per channel, with each channel able to handle continuous loads of up to 1.5A. In addition, the device supports the Infineon proprietary ‘DC Sensorless Field Oriented Control’ (DC-SLoc) technology for higher speed control of the motor.

The BU24035GW-E2 is able to provide the performance of a brushed or brushless DC motor controller without needing a sense amplifier. This is achieved by using the axis voltages of the motor as a feedback signal, allowing the controller to accurately track the motor’s speed and position. The device provides a high voltage input range of 8V to 36V, a configuration interface, diagnostic support, over-current protection and integrated MOSFET drivers. This all makes the BU24035GW-E2 an ideal solution for applications where high efficiency and high performance are of the utmost concern.

The BU24035GW-E2 works in the following way. Firstly, the voltage input is applied to the device, which is then converted into a regulated voltage by the power stage and used to drive the motor. The device then senses the rotor position through the back EMF, and uses this information to control the motor current, thereby adjusting its speed. The controller then regulates the current to ensure a consistent power delivery to the motor, allowing a range of different speeds, torques and frequencies.

The BU24035GW-E2 also has a range of integrated diagnostics and protection features to ensure robust operation. These include an internal current limiting circuit, over-voltage protection, over-temperature protection and a soft start feature. Furthermore, the device supports a range of safety related applications via its built in lock detection, short-circuit protection and stall detection functions. All these features help make the BU24035GW-E2 an excellent choice for applications requiring high performance, efficiency and reliability.

In conclusion, the BU24035GW-E2 is an excellent choice for powertrain related applications that require robust control of rotating machinery such as motors, blowers and pumps. Its integration of Infineon’s DC-SLoc technology, coupled with an extensive range of safety related features and a wide input voltage range make the BU24035GW-E2 ideal for applications where performance, efficiency and reliability are of the utmost importance.
