![]() Just select the PWP package which adds a ground PPAD connection under the chip. I mainly use the Altium Designer as a CAD tool, therefore I used the Altium plugin (figure-3). For the schematic symbol, footprint and 3D model, I used the free SamacSys tools, because it is time-consuming to design the symbols and component libraries from scratch and by datasheets information. The DRV8833 introduced a PWP 16-Pin HTSSOP package. As you can consider, there is no need to implement protection diodes or other extra components.įigure-2, Schematic diagram of the motor driver Be careful about its maximum rating which is 11.8V. The Vcc defines the motor supply voltage. The figure-2 shows the schematic diagram of the circuit. The VIL and VIH values show that the inputs can be used for both 3.3V and 5V logic without any problem.įigure-1, Logic level values for the DRV8833 chip The figure-1 shows the logic level thresholds of the chip inputs. The device includes a low-power sleep mode, which lets the system save power when not driving the motor.” The current regulation is a 20-μs fixed off-time slow decay. A simple PWM interface allows easy interfacing to the controller circuit. The DRV8833C can be powered with a supply voltage from 2.7 to 10.8 V and can provide output current up to 700-mA RMS. The device integrates two NMOS H-bridges and current regulation circuitry. ![]() According to the datasheet: “The DRV8833C device is an integrated motor driver solution for brushed DC or bipolar stepper motors. The DRV8833 chip is a dual H-bridge motor driver. For many low power applications, 1A to 1.5A RMS current consumption limit/per motor is enough, therefore I selected a useful chip that can operate with just a few external components. ![]() ![]() Full control over a DC motor is an essential function for a variety of applications. Motor driver circuits are one of the most useful designs for industrial, automotive and robotic applications. ![]()
