Using H-bridge as a driving device is popular and important in many consumer electronic applications, such as robots, DC/DC converters, D-class audio amplifiers and so on. Furthermore, the existence of dead time is necessary for the Hbridge driver to avoid the occurrence of shoot-through current. In this paper, based on the concept of OPA slew rate, a new deadtime generation is proposed to achieve more precise dead time compared with the conventional dead-time generators.
