8.3 System Example
To use the DRV2700 in a system, all that is required is a controller for the input signal and digital control, power management to provide power to the device, and a high-voltage load. Figure 8-17 shows a typical system diagram using the DRV2700 device. Because most systems already include some type of controller and power management, the DRV2700 device can easily be added to an existing system.
