Pinouts of one-channel controller
| PIN | Description |
|---|---|
| Vin | Motor supply voltage from 4.5 V to 28 V. It has protection against polarity change of supply voltage. |
| GND | System ground potential. |
| VM | Output providing access to the motor power supply after reverse polarity protection. It can be used to power other components of the system. |
| OUT1 | Outputs - to connect the motor leads. |
| OUT2 | Outputs - to connect the motor leads. |
| VCC | Logic voltage - 5 V. |
| OCC | In case of overcurrent, the controller is switched off. By default in low state. If it is in high state it will automatically try to resume operation after a short time interval. |
| EN | When in the low state, the OUT1 and OUT2 outputs are set to the high impedance state. Inverted Inverted PWM can be applied to this pin(When EN is in the high state and PWM1 or PWM2 in the high state).Default is in the low state. |
| ENB | When it is in high state,OUT1 and OUT2 outputs are set to high impedance state.PWM can be applied to this pin(When ENB is in low state and PWM1 or PWM2 in high state).Default inhighstate. |
| PWM1 | Control input for OUT1. Default is low. |
| PWM2 | The control input for OUT2. Default low. |
| OCM | Current monitoring output, pin provides an analog feedback voltage of approximately 500 mV per amplifier. |
| DIAG | Error diagnostics output. goes low when errors occur or the controller is disabled by EN or ENB. |
