TLE7183FXUMA2 application field and working principle

The TLE7183FXUMA2 is a highly integrated three-phase motor driver developed by Infineon Technologies AG, a leading provider in motor control and semiconductor solutions.

The TLE7183FXUMA2 is an enhanced version of the TLE7180FXMA2 and TLE7168FXMA2 products which offer several features and benefits. It is capable of driving three-phase brushless DC (BLDC) or three-phase permanent magnet synchronous motors (PMSMs). It has an integrated power module that can supply up to 2A and incorporates an MOSFET driver for the control of the motor. It also includes a Hall sensor interface and a pulse-width modulation (PWM) controller. This makes the TLE7183FXUMA2 ideal for applications such as electric pumps, fans, and drives in industrial and automotive applications.

Application Fields

The TLE7183FXUMA2 can be used in a wide range of applications, from small BLDC motors which power personal care applications, such as electric toothbrushes, to heavy-duty industrial motors. It is ideal for battery-powered, low-voltage applications thanks to its low quiescent current of only 300uA, while the integrated infrared (IR) ESD protection makes it suitable for use in the automotive industry.

Working Principle

The TLE7183FXUMA2 uses the Hall sensor inputs to detect the position of the motor\'s rotor. This data is then used to determine the motor speed, which is controlled by the pulse width modulation (PWM) controller. The integrated MOSFET drivers then control the power supplied to the motor, allowing the user to adjust the speed and torque of the motor. The PWM frequency can be adjusted from 500 Hz to 25 kHz, making it suitable for a wide range of applications.

In addition, the TLE7183FXUMA2 has an integrated over-current protection feature, which will shut down the motor if the current exceeds the preset level. This allows the product to protect the motor and other components in the system from damage due to over-current situations. Another safety feature is its over-temperature protection, which will turn off the motor if the operating temperature exceeds a certain level.

Conclusion

The TLE7183FXUMA2 is a highly integrated three-phase motor driver that is suitable for a wide range of applications in both industrial and automotive settings. Its integrated power module and MOSFET drivers make it ideal for controlling the speed and torque of motors, while its over-current and over-temperature protection features make it a safe and reliable product.
