Overview
The LV8044LP is a 6-channel motor driver IC for digital still camera.
Functions
Two microstep drive H-bridge driver channels.
Two microstep drive/PWM saturated drive switchable H-bridge driver channels.
Two constant-current drive H-bridge driver channels.
Drive mode switchable between 2-phase, 1-2 phase full torque, 1-2 phase, and 4W1-2 phase (channels 1, 2, 3, and 4).
Microstep drive step advance controlled by a single step signal input (channels 1, 2, 3, and 4).
Ability to set the hold current to one of four levels (channels 1, 2, 3, and 4).
Ability to set the constant-current reference voltage to one of 16 levels from the serial data (channels 5 and 6).
Eight-bit 3-wire serial control.
Three on-chip photosensor driver circuits.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.
Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device.
Maximum Ratings are stress ratings only.
Functional operation above the Recommended Operating Conditions is not implied.
