Controller pinouts
| PIN | Description |
|---|---|
| Vin | Motor supply voltage from 10 V to 47 V. It has protection against polarity change of supply voltage (up to 40 V). |
| GND | System ground potential. |
| VM | Output to provide power to the motor after reverse polarity protection. It can be used to power other components of the system. |
| A+ | Motor outputs A. To be connected for single channel mode. |
| A- | |
| B+ | B motor outputs. To be connected for single channel mode. |
| B- | |
| VCC | Adjustable 5 volt output. This pin gives access to the voltage from the TB67H420FTG internal regulator. The output should only be used for logic inputs as it can only provide a few milliamps. |
| INA1 | Control input forA+.PWM can be applied to this pin (usually PWMA in the high state). Default state is low. In single channel mode it controlsA+andA-. |
| INA2 | Control input forA-.PWM can be applied to this pin (usually PWMA in the high state). Default state is low. In single channel mode, controlsB+andB-. |
| PWMA | PWM input for channelA. Default state low. In single channel mode, the PWM input. |
| INB1 | Control input forB+.PWM can be applied to this pin (usually PWMB in high state). Default state is low. |
| INB2 | Control input forB-..PWM can be applied to this pin (usually PWMB in the high state). Default state is low. |
| PWMB | PWM input for channelB. Default state low. |
| LO1 | Error diagnostics output. Goes low when an error occurs due to excessive current or temperature. Default state is high. |
| LO2 | Error diagnostics output. Goes low when load or temperature fault occurs. Default is low. |
| VREFA | The output indicates the current threshold value for channelA.In single channel mode, outputs the current threshold value. |
| VREFB | The output indicates the current threshold value for channelB. |
| TBLKAB | Noise filter configuration pin for the constant current circuit. Default is low. Input should not be changed when the controller is powered. |
| HBMODE | Operating mode configuration input, High state for single channel mode, low state for dual channel trub.This input should not be changed when the controller is powered. |
