ATA6026 H-bridge Motor Driver

The ATA6026 is used to drive a continuous-current motor in a full H-bridge configuration. An external microcontroller controls the driving function of the ATA6026 by www.DataSheet4U.com providing a PWM signal and a direction signal, and allows the usage of the ATA6026 in a windshield wiper application, for example. The ATA6026 supports PWM and direction-cont.
