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.
