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.
