Regarding this issue, according to the specifications of the L9110S, it is a dual-channel DC motor driver chip that can drive two DC motors at the same time. However, the output current of the L9110S is limited to around 800mA, so it can only drive smaller power motors, which are typically suitable for small robots, smart cars, and other low-power applications. For high-power motors, you may need to use a more powerful motor driver.
The L9110S is a dual H-bridge driver chip that can be used to drive DC motors. It has a high current and voltage capacity and is able to provide enough power to drive large motors. Therefore, the L9110S can effectively drive large motors, and also has good performance in terms of control and protection.
