Product Overview
产品说明
LC898201 is the appropriate motor control LSI for the surveillance camera usage, and it can drive iris, focus, zoom and Day/Night switching simultaneously. It incorporates two feedback circuits for iris and focus control, and two stepper motor control circuits for zoom and Day/Night switching. Moreover, the feedback control applies iris control, and stepper motor controls apply focus, zoom and Day/Night switching at the mode selection. Stepper motor control circuits can drive the stepping motor efficiently(It is called “ECO(GREEN)-driver”).
