DESCRIPTION  
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.
