Specifically, this chip is able to accurately control a variety of electric loads, such as power seats, power windows and power sunroofs. Through precise control algorithms, the BTS50085-1TMA is able to realize on/off control and speed regulation of motorized loads, making these components run more smoothly in the process.


2. Electric drive system: BTS50085-1TMA can be used in electric drive systems such as electric cars, hybrid cars and electric motorcycles. It can accurately control the motor in the electric drive system and realize the functions of starting, stopping, accelerating and decelerating the motor. By integrating core functions such as current measurement, current limiting and over-temperature protection, the BTS50085-1TMA is able to monitor the motor's operating status in real time, ensuring safe and stable operation of the motor under various operating conditions.


3. Other applications: The BTS50085-1TMA can also be used in other applications that require high-side switching control. For example, by precisely controlling the charging and discharging process of the battery, it can effectively prevent overcharging, overdischarging, and overheating, thus guaranteeing the safety and durability of the battery.

In the electric braking system, the chip can precisely control the action of the braking motor to realize fast and smooth braking effect and enhance the safety performance of the vehicle.



Ⅵ. How to install BTS50085-1TMA?


First of all, we need to choose a suitable installation location for BTS50085-1TMA in the car electrical system. Generally speaking, the inside of the car door is the ideal choice because it can be directly connected to the power window mechanism. After selecting the location, it is important to make sure that it is stable and reliable, able to withstand vibrations and shocks generated by the car during driving to ensure the stable operation of the chip.


We then moved on to connecting the wires. These wires include key components such as the power supply, the ground wire, the power window switch and the power window motor. In this process, we must operate carefully to ensure that the power cord of the BTS50085-1TMA is accurately connected to the car's electrical system. In addition, to ensure circuit safety, we should also add appropriate fuses or overload protection devices as needed to prevent accidents caused by excessive current.


After the installation is completed, we also need to carry out a series of testing and commissioning work to ensure that the BTS50085-1TMA can work properly. This includes testing the switching function of the power windows and observing whether the windows can open and close smoothly as we expect. Only through these tests can we ensure the success of the entire installation process and allow the BTS50085-1TMA to perform as it should in the automotive electrical system.

Ⅷ. How to realize the overload protection function of BTS50085-1TMA?


First of all, BTS50085-1TMA is equipped with a dedicated current control input. This design allows us to flexibly adjust the current carried by the output through a PWM (pulse width modulation) signal. There is a clear proportional relationship between the current at the input end and the load current driven by the output end. This feature ensures the accuracy of current control. More importantly, BTS50085-1TMA also has a built-in current detection mechanism. When the load current unexpectedly exceeds our preset maximum value, this mechanism can quickly capture this abnormal situation and take necessary measures in a timely manner to ensure the stable operation of the entire system.


Secondly, once the BTS50085-1TMA detects an overload condition, its control logic will immediately activate the overload protection mechanism. Specific countermeasures may include turning off or limiting the output of the switch to prevent the current from continuing to increase and possibly causing circuit damage. In addition, the chip may also output an indication signal to notify the system that an overload event has occurred, so that the system can take appropriate measures, such as reducing the load or shutting down the system, to avoid further damage.


Finally, once the overload condition is eliminated, for example by removing or reducing the load, the BTS50085-1TMA automatically returns to normal operation. This is because its protection mechanism usually adopts an automatic reset design. Once the overload condition no longer exists, the chip will automatically release the protection state and restart its normal operation.
