IC L298 based bidirectional H bridge DC motor control circuit


Posted on Feb 5, 2014

A bidirectional H bridge DC motor control circuit is shown here. The circuit is based on the IC L298 from ST Microelectronics. L298 is a dual full bridge driver that has a wide operating voltage range and can handle load currents up to 3A. The IC also features low saturation voltage and over temperature protection. In the circuit diode D1 to D4 ar
