external pin.
•The 4-phase distributor switching timing can be set to occur either on both
rising and falling edge detection or on rising edge detection only with an
external pin (MODE3).
•A phase holding function is provided to prevent phase skip during switching
of excitation in the course of operation.
•The motor current is set by a voltage divider formed by an external resistor
connected to the Vref pin.
•The CLK input pin is provided with an internal noise filtering circuit in
addition to a Schmidt circuit to increase the margin for extraneous noise.
•When set low, the ENABLE pin turns off the motor drive current for all phases
and retains the phase excitation state.
