A3908 - Low Voltage DC Motor Driver

General Description

The A3908 is a low voltage bidirectional DC motor driver with a typical input voltage range of 3 to 5.5 V and output currents up to 500 mA.

The unique output full-bridge incorporates source-side linear operation to allow a constant voltage across the motor coil.

Key Features

  • Constant voltage operation (adjustable).
  • 500 mA output peak rating.
  • Low power standby mode.
  • Small 2 mm × 2 mm, 0.55 mm nominal height DFN package.
  • Typical input voltage range of 3 to 5.5 V.
  • Adjustable constant voltage or PWM operation.
  • Less than 500 nA standby mode current.
  • 40°C to 85°C operating temperature range.
