DC MOTOR 5 click carries the DRV8701 brushed DC motor gate driver from Texas Instruments. The click is designed to run on an external power supply. It communicates with the target MCU over the following pins on the mikroBUS™ line: AN, RST, CS, PWM, and INT.

DRV8701 driver features

The DRV8701 is an H-bridge gate driver (also called a pre-driver or controller). The device integrates FET gate drivers in order to control four external NMOS FETs. The device can be powered with a supply voltage between 5.9V and 45V.

Internal protection functions are provided: under-voltage lockout, charge pump faults, overcurrent shutdown, short-circuit protection, pre-driver faults, and overtemperature.

How the click works

The motor's velocity and direction can be adjusted with two PWM input signal's.

Code snippet

The following code snippet shows an example of DC motor 5 click usage. It will detect button press, and change the state of the control pins, putting the motor into one of the 4 possible states.

01 void main()
02 {
03     systemInit();
04 
05    while (1)
06     {
07         // Coast
08         if (Button(&GPIOD_IDR, 1, 1, 1))
09         {
10             IN1_PIN = 0;
11             IN2_PIN = 0;
12         }
13 
14        // Reverse
15         if (Button(&GPIOD_IDR, 2, 1, 1))
16         {
17             IN1_PIN = 0;
18             IN2_PIN = 1;
19         }
20 
21        // Brake
22         if (Button(&GPIOD_IDR, 3, 1, 1))
23         {
24             IN1_PIN = 1;
25             IN2_PIN = 1;
26         }
27 
28        // Forward
29         if (Button(&GPIOD_IDR, 4, 1, 1))
30         {
31             IN1_PIN = 1;
32             IN2_PIN = 0;
33         }
34 
35    }
36 }
