LV8041FN
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.
