LV8044LP
Overview
The LV8044LP is a 6-channel motor driver IC for digital still camera.
Function
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.
Built-in MO(stepping position detection monitor output) function.
Typical Applications
DSC
Security camera
CCTV
