Broadcom’s ADM1063ACPZ PMIC-Supervisor is designed for high-current, high-speed motor driver applications. The IC provides all the required control and monitoring functions for a motor driver power stage. The ADM1063ACPZ is particularly well adapted to meet the needs of applications such as drivable robotic arms and similar electric motor controllers. It is a complete three channel motor control system, with a full range of functions to allow for multi-quadrant drive development.

The ADM1063ACPZ meets applicable MIL-STD-1553B requirements for motor controllers. The device features 3 phase current feedback and provides high accuracy, linear phase current-sensing with gain and phase skew compensation, as well as a separate phase current drag control. Additionally, the device boasts low-phase current offset, wide open-loop gain control, and fast transient response, making it an ideal choice for high-speed motor applications.

The main features of the ADM1063ACPZ are its three channels, each of which can be programmed and configured independently. The power stage can be configured to provide three-phase sinusoidal, trapezoidal, or square wave output. Gain and phase error corrections can be applied to the output to improve linearity and accuracy. Additionally, drag control compensation is available to reduce current ripple during operation.

The ADM1063ACPZ also provides for over-voltage and over-current protection to ensure motor and motor driver safety. Over-current protection is provided by detecting a current limiting condition in any of the three motor phases. A hardware-activated over-voltage protection is also included with an adjustable threshold. Finally, the device has a power-down reset circuit to protect the motor during unexpected power loss or other fault conditions.

The IC\'s built-in voltage and current feedback channels make the ADM1063ACPZ ideal for applications requiring precise, high-current, high-speed motor control. The three independent channels enable different control schemes to be applied to different motors depending on their characteristics. Additionally, the device\'s built-in protection and feedback systems ensure that the motor and its driver are safe and reliable under all operating conditions.
