Input
Input
Input
ENABLE forcibly turns OFF all output transistors at operation.
Data such as electrical angle and operating mode are all retained.
STANDBY halts the charge pump circuit (power supply booster circuit) as well as halts output.
(At this time, data on the electrical angle are retained.)
W1-2 Phase Excitation
DATA MODE switches external duty control (forced PWM control) and constant current
CLK-IN control. In Phase mode, H-bridge can be forcibly inverted and output only can be
turned off. Constant current drive including micro-step drive can only be controlled in CLK-IN mode.
