<p>The L6234PD is a three-phase motor driver and controller designed to drive brushless DC (BLDC) motors up to 3A current. It can be used in many applications from Robot control, Industrial automation and consumer haptic applications. It is an integrated driver IC, meaning it can be used without any other external components, thus making it perfect for low-cost consumer applications.</p><p>The L6234PD employs a pulse-width modulated (PWM) signal for controlling the speed of the motor. It operates by periodically adjusting the ratio between on and off time of the PWM signal. The duration of each period is known as the ‘duty cycle’, and the ratio between its on and off times is known as the ‘commutation angle’. By varying the duty cycle or commutation angle, the motor can be adjusted to the desired speed.</p><p>The L6234PD is designed to provide a simplified interface to the motor, allowing users to easily implement the motor into their system. It has an onboard encoder with two independent pulse outputs, one for controlling the speed and the other for controlling the direction. It also features an array of integrated features to improve motor performance, such as an adjustable over-current protection, a commutation up-time limit and a soft start mode.</p><p>In addition to driving the motor, the L6234PD can be used as a controller. It has an onboard I2C interface that allows the user to access to a range of control features. These include over-temperature protection, an adjustable current limit and a speed control curve. These features allow the user to tailor the motor’s performance to their specific application requirements.</p><p>The L6234PD can be used in a wide range of applications. It is suitable for applications requiring high speed, low cost and low power consumption such as Haptic feedback, robotics, and industrial automation. It also can be used in applications requiring more precise control such as surgical robotics, and medical device operation.</p>
