APPLICATIONS
● Office photocopiers, printers, etc.FEATURES
● Entry of external clock is enough to activate the micro step sinusoidal driver.● The excitation mode of 2, 1-2, W1-2, 2W1-2, or 4W1-2 can be selected with the 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. Semiconductor Components Industries, LLC, 2013 June, 2013 91212HKPC 018-08-0108 No.A0752-1/1...
