Connectors www.ti.com 4 Connectors 4.1 Motor Outputs The connector J2 should be connected to the motor terminals. Each pin in this terminal is labeled on the EVM itself as AOUT1, AOUT2, BOUT1 and BOUT2. The polarity of these connections will affect the direction of the motor in the case of a brushed DC motor. In case of a stepper motor, one winding should be connected to AOUT1 and AOUT2, while the other should be connected to the outputs BOUT1 and BOUT2. Refer the datasheet for further information. 4.
LED (D1) 7 www.ti.com LED (D1) The diode D1 indicates the status of the nFAULT signal. When there is a FAULT condition on the DRV8833, this LED lights up. The two possible fault conditions are over current and over temperature. Refer to the schematic / datasheet for more information. 8 Test Points Kelvin connections are provided for all pins of DRV8833. They are appropriately labeled on the EVM.
