Abstract

This article discloses a circuit configuration with a particular topography that prevents large current surges in a motor driver due to false triggering of a motor brake, thereby eliminating the shorting out of the motor driver. The disclosed technique prevents, due to a fault condition, the motor brake and the motor driver from being in the conducting state at the same time.
