7 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.

These test points can be used to measure the status of the pin or can be connected to the Sense of the

controlling instrument.

9 Current Sense Resistors (R5, R6)

R5 and R6 are the current sense resistors directly connected to AISEN and BISEN respectively. The other

side of this resistor is connected to GND. The value of this resistor is chosen to be 0.15 Ω. This value

controls the current through the DRV8833 to be 1.33 A. To change this value of regulating current, this

resistor value must be changed as mentioned in the datasheet.
