SOF Pin (“Soft Off” Function) Operation [LB1848M only]
The soft off function reduces power supply line noise due to the kickback current generated when the stepping motor
drive mode is switched from drive to standby. The “soft off” function provided by this IC operates when a capacitor
(0.001 to 0.01 µF) is connected between the SOF pin and ground. (Leave the SOF pin open to disable the soft off
function.)
The waveforms for each pin are shown below.
