    Products Detail

    STK621-738-E Overview


    In this package, Tube is used.In order to save costs, H bridge is included in the 29-SSIP Module, 21 Leads, Formed Leads package.Bridge driver is possible to ensure improved reliabilbridge drivery by varying the supply voltage of 12.5V~17.5V.H bridge circuit is mounted in the way of Through Hole.Motor driver H bridge works normally at -20°C~150°C TJ's operating temperature.AC Motors is pretty useful in a variety of applications.On PCBs, Through Hole mounts H gate.Among full bridges specific characteristics is Auto Restart, Bootstrap Circuit, Status Flag.Transmission lines are terminated with 21 terminations with the H bridge that matches their characteristic impedance.Signal interfaces use 21 pins as pronged contacts.There is a voltage supply of 15V that is used to operate H bridge circuit.The maximum load current a power supply can provide at a specified ambient temperature is 30A.As part of the Motion Control Electronics subcategory, this H bridge motor driver has various similarities to other parts in this category.To provide high efficiency, the supply voltage is maintained at 280V.The electric power supplied by 15V is used to power the electrical load.
