Description of product: MC33926 dual - channel driver engines 28V/2.5 A

The module is based on a MC33926 allows you to control two motors with a supply voltage of 28 Volts max continuous current consumption to 3 A (when using proper cooling). The driver stand also seconds jumping current up to 5 A. the Speed of rotation can be controlled by using PWM up to 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.

Insights driver engines





The power supply for the motor (5V-28V).
The potential mass.


Channel output-driven inputs M1_IN1 and M1_IN2.
Channel output-driven inputs M1_IN1 and M1_IN2.
PWM / D2Entrance 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 /D1Entrance 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.



Control inputs and outputs M1_OUT1 M1_OUT2. The default output in the high state.
Control inputs and outputs M2_OUT1 M2_OUT2. The default output in the high state.
VDDOutput voltage 3V-5V. It is recommended to use only for the inclusion of the SF contact in the high position.
SFThe 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. 525mV at 1A. 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.

Heat dissipation

The MC33926 chip that was used in the module has a maximum continuous current up 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 radiator which can be installed using glue termoprzewodzącego.

Diagram of the module

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.
