PMIC - Motor Drivers, Controllers – DRV8860PWR Application Field and Working Principle

DRV8860PWR is a full-featured motor driver integrated circuit (IC) designed for the tactical control of two winding motors in applications such as cartesian robots, precision positioning, CNC machining and automation applications. It is the R2 version within the Texas Instruments DRV88x series and its main features include two 50V output channels, direct PWM input control and an adjustable current limit.

Application Field

DRV8860PWR has a wide range of applications that makes it an ideal fit for an array of industrial and robotic installations. These devices are most commonly used in the following applications:

• Machine shop CNC equipment;
• Industrial automation;
• Laser cutting machines;
• Food processing machines;
• Robotic arms;
• Medical devices.

In addition to its industrial and robotic uses, the DRV8860PWR motor driver can also be used in other less demanding applications, such as motorized toys. This device is also an ideal fit for those who are building their own robots since it offers full wireless control, making the programming and tweaking of the robot circuit straightforward.

Working Principle

The DRV8860PWR full-featured motor driver offers a wide range of speed and torque outputs. It operates using Pulse Width Modulation (PWM) to control the speed of the motor and the amount of torque delivered. To supply the output power the device requires a PWM signal, which can either come from an external source, or built into the motor driver (DRV8860PWR). The PWM signal is then integrated with the current sense amplifier which maintains the current of the motor within the pre-defined level of the current limit for the application.

The DRV8860PWR full-featured motor driver also features an adjustable current limit. This allows for the user to adjust the current going to the motor. This can be helpful when testing different motors or when more precision is needed. This adjustable current limit also ensures that the motor does not draw too much current and the device is protected from the extra power.

DRV8860PWR motor drivers also offer both thermal and over-voltage protection. The thermal protection prevents damage to the motor driver while the over-voltage protection keeps the circuit safe from unexpected power surges. Furthermore, the DRV8860PWR driver also allows for multiple sources of supply, including 12V and 24V power sources, which makes it extremely versatile in terms of the applications it can be used in.

Conclusion

The DRV8860PWR motor driver offers a highly reliable, full-featured solution for those who need an integrated motor driver for a range of industrial and robotic applications. With its wide range of features such as wireless control, adjustable current limit and thermal and over-voltage protection, it is an ideal fit for those who are looking for a robust, easy-to-use motor driver.
