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.
