Toshiba stepping motor driver ICs overcome common application challenges by employing Active Gain Control (AGC) and Advanced Dynamic Mixed Decay (ADMD). Stepping motor drivers are widely used for precise position control. However, stepping motors typically require high current operation to maximize speed and prevent stalls or rapid current decay during PWM off periods. This can lead to noise and vibration issues. Designers are seeking optimized control solutions. AGC and ADMD address these issues and are implemented in most of Toshiba's stepping motor controller products.
