DRIVING APPARATUS HAVING CURRENT DETECTION AND DRIVING APPARATUS FOR MOTOR HAVING CURRENT DETECTION

摘要

The present invention relates to a driving apparatus having a current detection function and a motor driving apparatus having a current detection function that are capable of detecting current without a voltage drop by using a dummy transistor connected to a driving transistor in parallel. The driving apparatus includes: a driving unit including at least one transistor connected between a driving power terminal supplying driving power and a ground and switched according to switching control signals to drive a preset device; and a detecting unit including at least one dummy transistor connected to the at least one transistor in parallel and switched together with the at least one transistor according to the switching control signals to detect current flowing in the at least one dummy transistor.
