EVAL-CN0196-EB1Z, H-Bridge Evaluation Board Using ADuM7234 Isolated Half-Bridge Drivers

Beschreibung

• EVAL-CN0196-EB1Z, H-Bridge Driver Evaluation Board using isolated half-bridge drivers. CN0196 is an H-bridge composed of high power switching MOSFETs that are controlled by low voltage logic signals. The circuit provides a convenient interface between logic signals and the high power bridge. The bridge uses low cost N-channel power MOSFETs for both the high and low sides of the H-bridge. The circuit also provides galvanic isolation between the control side and power side. This circuit can be used in motor control, power conversion with embedded control interface, lighting, audio amplifiers, and uninterruptable power supplies (UPS). The ADG787 is a low voltage CMOS device that contains two independently selectable single-pole double-throw (SPDT) switches. With a 5 Vdc power supply, a voltage as low as 2V is a valid high input logic voltage
