How is the single chip machine controlled
Using a dedicated drive circuit like UN2003, such as the darlington array or L298N, you can also build your own H bridge.
The single chip machine only outputs the signal, which is driven by the isolated circuit and the power switch circuit. Control ordinary three asynchronous motor can microcontroller output signal after the triode drive a small power relay, ac contactor, driven by relay and motor control. It can also be used as a single chip to drive the power relay directly after the triode is enlarged. There are a lot of methods. As for the driver servo, the signal of the single chip port can be directly driven by the decoupled isolation, and the actuating signal required by the servo driver itself is a weak signal.

A single chip can't be loaded directly, because his current is small, it's better to have a light decoupled action and it can also be used to boost the circuit. The booster signal is used to control the switch device to control the motor.
