Analog input voltage control the driving current which is in proportion to input voltage. This control is direct PWM control type of motor current chopper. Also,built-in the current limit circuit. This IC controls the motor current directly. direct PWM operation as follows; 1) The current which flows on a motor is detected, and current is supplied from a power supply until it reaches the predetermined instruction value to which the current is proportional to input voltage. 2) When current reaches an instruction value, an output transistor is changed and the period coil inertia energy to a career cycle is made to regeneration using an internal path. 3) After repeat 1) and 2). Therefore, the IC constantly surveillance and control the current value itself use sensor resistor. Moreover, these ICs built-in current limit circuit so that protect to large current.
