The SLA7062/67 chip is a unipolar driver capable of delivering up to 3 amps. This chip is somewhat difficult to locate and is priced at approximately $10 each. Availability was confirmed through a Google search, which yielded three units necessary for prototype development. Newark (Farnell) offers these chips but currently has no stock. The printed circuit boards (PCBs) can be obtained from BatchPCB, and the bill of materials (BOM) along with the circuit diagram is provided below. This board utilizes a 10-pin IDC connector (PMinMO) and is compatible with the CNC USB Motion Controller.

The SLA7062/67 unipolar driver chip is designed for applications requiring moderate current control, making it suitable for various automation and motion control projects. The chip's ability to provide up to 3 amps is particularly beneficial for driving motors or actuators in CNC machinery, robotics, and other electromechanical systems.

The circuit schematic typically includes the SLA7062/67 connected to a power supply that meets the voltage requirements of the chip. The input control signals are routed to the chip's control pins, which dictate the operation of the output stage. The inclusion of a 10-pin IDC connector (PMinMO) facilitates easy interfacing with other components, such as microcontrollers or motion control systems, ensuring a seamless integration into existing setups.

The PCB layout designed for the SLA7062/67 should consider thermal management and component placement to minimize noise and interference. Proper decoupling capacitors should be placed near the power supply pins to stabilize the voltage levels and filter out high-frequency noise. Additionally, the BOM will list all necessary components, including resistors, capacitors, and any additional drivers or protection diodes required for optimal performance.

For users looking to implement this driver in their projects, sourcing the SLA7062/67 chips from alternative suppliers may be necessary if stock is unavailable at Newark (Farnell). BatchPCB provides a reliable option for obtaining custom PCBs, allowing for flexibility in design modifications as needed.
