A3981KLPTR-T General Description
The A3981KLPTR-T is a top-of-the-line stepper motor driver IC specifically designed for automotive applications, offering a wide operating voltage range of 3V to 50V. This versatility makes it an ideal choice for various automotive systems such as seat control, HVAC systems, and electronic throttle control. With its 18-pin surface-mount package design, the A3981KLPTR-T provides superior performance, offering up to 50% higher current output compared to similar devices. This makes it well-suited for driving larger stepper motors in automotive applications, providing the power and reliability needed for demanding automotive systems. Additionally, the A3981KLPTR-T features built-in protection measures including overcurrent, thermal, and under-voltage lockout protection, ensuring the safety of both the system and its components. Furthermore, this high-voltage, high-current stepper motor driver IC supports micro-stepping and is capable of driving bipolar stepper motors with full H-bridge control, offering precise control over motor speed and position. Designers can take advantage of this flexibility to create innovative and efficient automotive system designs, making the A3981KLPTR-T a standout choice for automotive applications
