Features
Integrates the actuator drivers required in a digital camera on a single chip
(1) Two focus motor constant voltage H-bridge drivers : can be used as a single stepping motor driver
Constant voltage drive
Supports both single-phase and 1-2 phase drive
The voltage for each constant voltage channel can be set independently
(2) One shutter actuator constant current H-bridge driver : can be used as a voice coil motor driver
Constant current drive
The current level can be set independently for each excitation direction → Supports current limitation when the
shutter is open.
Stable response speed during continuous drive provided by rapid charge and rapid discharge circuits
Supports constant current rising waveform correction using an external RC circuit (The external RC components are
not required when correction is not used.)
→ Changes in the coil current rise due to supply voltage fluctuations are suppressed.
Includes regenerative braking logic
(3) Two aperture or zoom actuator low saturation voltage H-bridge drivers : can be used as a single stepping motor driver
Constant voltage drive
Supports both single-phase and 1-2 phase drive
(4) One zoom or aperture actuator constant voltage H-bridge driver : can be used as a single DC motor driver
Constant voltage drive
Can be switched between constant voltage drive and low saturation voltage drive → Switched by the IN13 input logic.
Built-in short-circuit braking function
Monolithic Digital IC
Digital Camera Motor Driver
