产品信息

The LV8044LP is a 6-channel motor driver IC for digital still camera.
  • 64step Micro-step Drive
  • Built-in Photo Sensor Drive Transistor
  • Stand-by Current: 0µA
  • Built-in TSD circuit
  • Low Output ON- Resistance : 1.4ohm(Io=0.4A)
  • 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.
