A3903 - Low Voltage DC Motor Driver

The A3903 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 sourceside linear operation to allow a constant voltage across the motor coil.

This regulated output minimizes motor
