The TLE7189FXUMA2 is a monolithic integrated circuit that provides comprehensive protection and control of 3-phase permanent magnet synchronous motors (PMSMs), BLDCs, and AC induction motors. This IC is designed based on the latest automotive technologies and is optimized for robustness and reliability. It offers protection against short-circuits, over-current, over-temperature, over-voltage, and under-voltage conditions. Additionally, it provides a wide range of working speeds and power levels.

The TLE7189FXUMA2 is part of the PRETRONICS family of motor control and driver ICs, offering an ideal solution for applications requiring an extremely compact, reliable and cost-effective motor control and protection solution. The TLE7189FXUMA2 provides a 3-phase driver and protection/monitoring signaling for sensors, which is available for external monitoring. Additionally, it features regulated current measurements for each output channel for motor current feedback.

The TLE7189FXUMA2 works by monitoring the motor\'s 3-phase current drawn from its 3-phase connection. It then uses this data to accurately control the motor\'s speed and torque. A range of parameters are adjustable by a microcontroller for optimized control and protection in a variety of motors. The embedded drivers automatically adjust the speed and current strength of the motor in order to control the speed, direction and torque of the motor and to maximize efficiency.

The TLE7189FXUMA2 also provides protection against over-voltage, under-voltage, over-temperature and short circuit faults. It has an integrated over-voltage and under-voltage protection circuit that monitors the phase and neutral line voltages. This is designed to automatically disconnect the motor when the voltage exceeds the set threshold. Additionally, the integrated thermal protection circuit monitors the die temperature and will automatically shut down the motor if the temperature exceeds the defined set point.

The TLE7189FXUMA2 is ideally suited to applications requiring reliable motor control across a wide range of speeds and power levels. Typical applications include automotive applications such as room-air conditioner drives, car comfort systems and electric vehicle (EV) motor drives, home appliance applications such as washing machines, dishwashers and air conditioners, and industrial applications such as IoT applications, industrial automation, robotics, and e-bikes.
