12.3.5 Brake Function

The BRAKE pin provides a means to turn on all the low-side GaNFETs, independent of INHx and INLx pin status. The brake pin has an internal pull down. Connect the BRAKE pin to GND externally if not used. A logic high on the BRAKE pin places the device into brake by turning on all the low-side GaNFETs.

Note: Use caution while applying the BRAKE high command, as this can cause very high current driven by the motor back EMF. During BRAKE operation, the maximum current through the GaNFET must be a value that is within the operating limits of the GaNFET current and junction temperature .
