Features
An actuator driver for single focus digital camera is implemented on a single chip.
(1) Supports a constant voltage for the AF H-bridge
×2 : a stepping motor (STM) ×1.
- Constant voltage drive.
- Enables 1-phase, 1-2 phase and 2-phase excitation.
- VC1 and VC2 allow the constant voltage for each channel to be set independently.
(2) Supports a constant current for the shutter H-bridge
×1 : a voice coil motor (VCM) ×1.
- Constant current drive.
- A fast charge/discharge circuit allows for stabilization of response speed for the continuous drive mode.
- Allows offsetting of the constant current rising waveform with an external CR.
(The external CR is not required when an offset is not performed.)
→ Prevent current rising variation of coil caused by supply voltage fluctuation.
- Implements regenerative brake logic.
(3) Supports a constant voltage for the iris H-bridge
×1 : a voice coil motor (VCM) ×1.
- Constant voltage drive.
- VC4 allows the independent constant voltage to be set.
