Pregled izdelka

The DRV201AEVM is an evaluation board to assist in evaluating the DRV201A IC as a voice coil motor (VCM) driver for camera autofocus. The device is an advanced voice coil motor driver for camera auto focus. It has 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. Device has 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 has also VCM short and open protection functions.
  • Configurable for linear or PWM mode VCM current generation
  • High efficiency PWM current control for VCM
  • Advanced ringing compensation
  • Integrated 10bit D/A converter for VCM current control
  • I2C interface
  • Improved PWM to linear mode settling time vs. DRV201
  • Improved EMC performance vs DRV201
  • Open and short circuit detection on VCM Pins
  • Internal current limit for VCM driver
  • 6 ball WCSP package with 0.4mm pitch

Področja uporabe

Imaging, Video & Vision, Consumer Electronics, Multimedia

Opozorila
