The DRV201A is an advanced voice coil motor driver for camera auto focus. It has an integrated D/A converter for setting the VCM current. VCM current is controlled with a fixed frequency PWM controller or a linear mode driver. Current generation can be selected via I2C register. The DRV201A has an integrated sense resistor for current regulation and the current can be controlled through I2C.

When changing the current in the VCM, the lens ringing is compensated with an advanced ringing compensation function. Ringing compensation reduces the needed time for auto focus significantly. The device also has VCM short and open protection functions.
