DRV201 - Voice Coil Motor Driver

Description

The DRV201 device 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.

Features

  • 1 Configurable for Linear or PWM Mode VCM Current Generation.
  • High Efficiency PWM Current Control for VCM.
  • Advanced Ringing Compensation.
  • Integrated 10-bit D/A Converter for VCM Current Control.
  • Protection.
  • Open and Short-Circuit Detection on VCM Pins.
  • Undervoltage Lockout (UVLO).
  • Thermal Shutdown.
  • Open and Short-Circuit Protection on VCM Output.
  • Internal Current Limit for VCM Driver.
  • 4-kV ESD-HBM.
