SA8301 Motor Drive IC compatible with TC118SS SA8301 is a single-channel low on-resistance DC motor drive integrated circuit designed for systems operating at low voltage.
MCU - resistor - transistor (1~2) - DC motor (plus diode protection). The speed can be controlled by controlling the pulse duty cycle only by programming the single chip computer. The lower the pulse duty cycle, the lower the speed; The higher the pulse duty cycle, the higher the speed.
