PIN | Default State | Description |
---|---|---|
VIN | Reverse-protected motor power supply input. While the driver can operate from a motor supply of 0 V to 11 V, the reverse-protection circuit will start negatively affecting performance below a few volts, and 1.5 V is the lower limit of where it can be used. Power can be supplied directly to VMM to bypass the reverse-protection circuit. | |
VCC | 1.8 V to 7 V logic power supply connection. Logic supply current draw is typically only a few milliamps at most, so in many applications this pin can optionally be dynamically powered by a microcontroller digital output. | |
VMM | This pin gives access to the motor power supply after the reverse-voltage protection MOSFET (see the board schematic below). It can be used to supply reverse-protected power to other components in the system. It is generally intended as an output, but it can also be used to supply board power (such as in cases where the motor supply voltage is too low for the reverse-protection circuit). | |
GND | Ground connection points for the motor and logic power supplies. | |
AOUT1 | The motor A half-bridge 1 output. | |
AOUT2 | The motor A half-bridge 2 output. | |
BOUT1 | The motor B half-bridge 1 output. | |
BOUT2 | The motor B half-bridge 2 output. | |
AIN1/APHASE | LOW | A logic input control for motor channel A. |
AIN2/AENABLE | LOW | A logic input control for motor channel A. |
BIN1/BPHASE | LOW | A logic input control for motor channel B. |
BIN2/BENABLE | LOW | A logic input control for motor channel B. |
MODE | LOW | Logic input that determines the control interface. Logic low on this pin results in IN/IN mode while logic high results in PHASE/ENABLE mode. |
