  3. In the circuit of Figure 1, assume that a brush-type dc motor must drive a load back and forth between two endpoints on a lead screw. Optical sensors determine end of travel, and an SPDT switch selects to which end to send the load. The sensors ...

  4. Circuits Supply Power Vishay BYV26C BYV28-50 IRFP450 UF5406
    A simple high-voltage MOSFET inverter solves the problem of driving a high-side MOSFET, using a low-voltage transistor, Q 1 , and a special arrangement involving D 6 (Figure 1). This inverter is much faster than those that optocouplers drive, so ...

  2. Circuits Analogue Design Power ON Semiconductor MC33072 PN200A BD135G BD136G
    P-channel MOSFETs can simplify designs when you use them as high-side switches on circuits with voltages exceeding 100 V dc. When driving a MOSFET, you must rapidly charge and discharge the input capacitance between its gate and its source to ...
