Description of operation
Input Pin Function
(1) Chip enable function
(2) Drive mode switching pin function
STM mode (DM = Low or Open)
(1) STEP pin function
(2) Excitation mode setting function
(3) Position detection monitoring function
The function to prevent including the turn from the input to the power supply is built into each input pin.
Therefore, the current turns to the power supply even if power supply (VM) is turned off with the voltage impressed to
the input pin and there is not crowding.
This IC is switched between standby and operating mode by setting the ST pin. In standby mode, the IC is set to
power-save mode and all logic is reset. In addition, the internal regulator circuit and charge pump circuit do not
operate in standby mode.
The IC drive mode is switched by setting the DM pin. In STM mode, stepping motor channel 1 can be controlled by
the CLK-IN input. In DCM mode, DC motor channel 2 or stepping motor channel 1 can be controlled by parallel
input. Stepping motor control using parallel input is 2-phase or 1-2 phase full torque.
This is the initial position of each excitation mode in the initial state after power-on and when the counter is reset.
The MONI position detection monitoring pin is of an open drian type.
When the excitation position is in the initial position, the MONI output is placed in the ON state.
(Refer to "Examples of current waveforms in each of the excitation modes.")
