The module is based on a MC33926 lets you control the motors with a supply voltage up to 28 Volts and a continuous current consumption of up to 3 A. (with appropriate cooling). The driver stand also seconds jumping current up to 5 A. the Speed of rotation can be controlled by a signal PWM with a frequency of 20 kHz. Analog output FB allows you to measure the current consumption of the motors with tenderness 0,525 V/A. the Module has reverse too high current and overheating the system. Details in the documentation.
|Powered engines (5 V-28 V).|
The potential mass.
|Outputs to motor inputs IN1 and IN2.|
|Control inputs outputs OUT1 and OUT2. The default output in the high state.|
|PWM / D2||Entrance lock - on the contrary. When D2 is in a state of more low, the outputs OUT1 and OUT2 in the high impedance state. The input PWM is not inverted. The filler 70% for the controller also gives 70% for the engine . The default output in the low state.|
|PWM /D1||Entrance lock. When D2 is in a high state, outputs OUT1 and OUT2 in the high impedance state. Input PWM canceled Application fill 70 %, the engine 100 %-70 %, or 30 %. The default output in the high state.|
|VDD||Output voltage 3 V-5 V. Zalece only be used to enable contact SF in the high position.|
|SF||The status flag indicating too high current or short circuit. Default in the high state. In case of problems appears low state. The default output in the high state.|
|Output, which can measure the flowing current. The voltage rises. 525 mV at 1 A. the default Output in the low state.|
|The sleep state. When will be filed low, both channels will be in low power mode. The default output in the low state.|
|The timing of the rise slopes of the output voltage. Low as slow growth (1,5 us - 6 and us). High - a rapid increase (of 0.2 us - 1,45 gb). For PWM frequencies above 10 kHz, it is recommended to select a fast slew. The default output in the low state.|
|High, makes control inputs IN1 and IN2 for both channels. The default output in the low state.|
The dimensions of the module is a rectangle of size 25.4 mm x 30.5 mm.
The MC33926 chip that was used in the module allows to flow the current value to 5 A. But without applying proper cooling the driver will overheat at lower currents. For example, at room temperature, the driver is able to deliver 5 amps for about 5 seconds, and 4 And approx. 18 sec. After this time temperature protection exclude the layout. The consumption of 3 And the defense will begin in a few minutes. To increase the capabilities of the current chip, you need to install the radiatorwhich can be installed using adhesive, thermo-conductive.
The system includes components required for correct operation of the driver. Conclusions are popular goldpin connectors (2.54 mm pitch), thanks to which the system can be connected using wires.
