In summary, there are many applications for 3-15 V_DC motor drivers, including security cameras, video projectors, toys, and valve control in water and gas applications. onsemi current products are developed on a DMOS process technology that employs a low Ron FET. A bipolar process would have to use a transistor, which consumes more power. Most of Sanyo’s 3-15 V_DC motor drivers are monolithic ICs. There are four types of motor drivers, with different voltage levels and control methods. There are two control methods for the 3–5 V_DC motor drivers; PWM current control uses internal control to do the chopping, whereas the full-on type is controlled externally for the chopping. For the 5–15 V_DC motor drivers internal PWM control is used for high precision such as micro-stepping, the full-on method is used when simplicity and cost are the priorities.
