Seven-Channel Motor Driver IC
for Digital Cameras
Overview
The LV8041FN is a digital camera motor driver IC that integrates seven driver channels on a single chip.
Features
• Two PWM current control microstepping drive stepping motor driver channels
• One constant current forward/reverse motor driver
• Two PWM drive forward/reverse motor driver channels (one channel of which can be switched to function as a
microstepping drive stepping motor driver)
• Stepping motor drivers 1 and 2 support 2-phase, 1-2 phase, 2W1-2 phase, and 4W1-2 phase drive.
• Stepping motor driver 3 operates in fixed 2W1-2 phase drive mode.
• Microstepping drive step advance can be controlled with a single clock input (stepping motor drivers 1, 2, and 3)
• The constant current control chopping frequency can be adjusted with an external resistor (stepping motor drivers
1, 2, and 3)
• Phase detection monitor pins provided (stepping motor drivers 1, 2, and 3)
• The states of all of the drivers can be set up and controlled over an 8-bit serial data interface.
