Driver

Drive type IC is also called All in one IC, divided into single-phase drive type and two-phase drive type.
Built-in Hall element, dynamic offset correction, voltage regulator, overheating and power failure protection and a pair of complementary power output pins (DO, DOB).

The output pin has a built-in chopping diode to protect the output pin from being injured by the coil back electromotive force. It also has built-in PWM speed control, FG/RD output detection signal and lock protection functions.
