The AH286-PL-B is an automotive grade, Polyphase Brush DC Motor controller with integrated protection and diagnostic circuitry and IGBT based power stage. It is used to control electric motors such as brushed and brushless DC electric motors, or other air/hydraulic-powered motors. The product is equipped with an embedded microcontroller for maximum flexibility and offers different solutions for controlling motor speed, current and torque based on the specific application.

The AH286-PL-B is ideal for motor drivers and controllers in a variety of automotive applications including automotive power window, seat adjuster, sunroof and wiper, as well as electronic fuel injections and electric wastegate controllers. The controller also has various protection features such as overload protection, over current protection, over temperature protection, and under voltage protection.

The AH286-PL-B supports a wide range of input voltage, current, and speed control profiles, with adjustable current and speed limits. The controller supports both open loop and closed loop control, with digital signal processing (DSP) and digital to analog converters (DAC) providing precise and efficient control over motor speed and current.

In its operation, the AH286-PL-B utilizes a series of control signal inputs such as PWM (pulse width modulation), CAN (controller area network) and SPI (serial peripheral interface) to determine a motor’s torque, speed and current capabilities. This makes it possible to precisely and quickly control a motor’s speed and torque. In addition, the controller includes on-board current and temperature monitoring, providing additional protection and diagnostic capabilities.

The AH286-PL-B also includes integrated fault protection circuitry and various self-diagnostics features such as open circuit and short circuit detection. This ensures the motor remains safe and will not overheat or get damaged due to overloads of power or current. Finally, the AH286-PL-B is designed with a low standby power state and low power operation, making it suitable for use in battery operated systems.

In summary, the AH286-PL-B controller is used in combination with IGBT based power stages and other power conversion methods to create an effective and efficient motor driver and controller. Equipped with an embedded microcontroller, the controller provides flexibility, protection, and diagnostic capabilities. It supports a range of input voltage, current and speed control options, and digital signal processing and analog conversion provides precise and reliable control over the motor speed and current. Finally, the controller includes integrated fault protection circuitry and self-diagnostics features for added safety and reliability.
