LV8044LP
Bi-CMOS LSI
For Digital Still Camera
6-channel Motor Driver IC
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.

Notes
*1: This serial data is only accepted when the IN51/IN52 pulse inputs are in the Low/Low states, respectively. It is
ignored at all other times.
*2: This serial data is only accepted when the IN61/IN62 pulse inputs are in the Low/Low states, respectively. It is
ignored at all other times.
*3: When D4 = 1, MO is only output if microstep mode is selected for channels 3 and 4. In PWM mode, this output is held
fixed at the high level.
*4: The MO output can be specified to be the 1-2 phase position only in 4W1-2 phase excitation mode. In all other
excitation modes, the MO output position becomes the initial position regardless of the serial data values.
