Aptinex L Dual Full bridge Motor Driver Module

Although the device guarantees the absence of cross-conduction, the presence of the intrinsic diodes in the POWER DMOS structure causes the generation of current spikes on the sensing terminals. By using mixed technology it has been possible to optimize the logic circuitry and the power stage to achieve the best possible performance.

When the output switches from high to low, a current spike is generated associated with the capacitor C1. Implementing fast decay mode chopping using the L Home Questions Tags Users Unanswered.
