Driver based on the MOSFET allows you to control one DC motor is supplied with the voltage from 5.5 V to 40 V with current consumption of up to 12 A.
The slats were deployed on both sides of the module. After one of the connectors is responsible for the control and power supply of the logical part. On the opposite side is the power contacts of the motor (V+, GND) and outputs (OUT, OUTB). The voltage value of the control signals must be in the range from 3.5 V to 5.5 V. the Manufacturer recommends does not work at the voltage of 3.3 V.
In a standard installation requires connection of the PWM signal and to a contact select the direction of motor rotation DIR. Flags FF1 and FF2 indicate incorrect operation of the system. Pin RESET to default selected to supply.When the status is restored low, the system will go into a state of minimal energy consumption. Will reset all flags.
The system is based on MOSFET transistor with channel N IRF7842PbF with the channel resistance of 5 megohms. Details in the documentation.
|V+||Motor power supply (5.5 V-30V). The conclusion is denoted by the symbol + is the positive pole connections of the capacitor. Less output V+ allows you to control the power of the engine. Not recommended for high currents.|
|5V (out)||The output of the voltage regulator is 5V. The output current to a few mA. Be careful to avoid a short circuit with the adjacent terminal V+ as it leads to irreversible damage of the module.|
|GND||The potential of mass of the system.|
|Insights for the DC motor.|
|PWM||Signal speed control. Default in the low state|
|DIR||The choice of the direction of rotation of the motor. In the high state, the current flows from the output OUT to OUTB. By default, the floating state (float).|
|RESET||After filing lowest position the system is in a low power state. Removes all the flags.|
|Status flags system. In the event of an error, the status is high.|
|H||L||Temperature too high||NOT|
|Voltage too low||SO|
The module includes: a circuit Board with installed systems conclusions and capacitor, which must polutować.
