    IGBTs are a new class of high voltage insulated gate bipolar power semiconductors that combine the advantages of MOS gate drive simplicity with the current handling capability of bipolar devices. A brief explanation of the physics and the structure of the device is given and the characteristics which make IGBTs the best choice for automotive ignition power switches are pointed out View full abstract»

    After a period of fast growing technology developments, cost has become an important issue for the potential users. The apparition of good targeted discrete products for specific applications: auto protected Darlingtons, Sensefets and also more dedicated low cost ICS, has brought some opportunities to the design decision markers in the power application field. A wide technology palette is now avai... View full abstract»

    The authors describe a monolithic stepper motor driver designed mainly for computer peripheral applications. Realized in a mixed bipolar/CMOS/DMOS technologym it combines on the same chip four isolated 100 V 1.2 ohm DMOS transistors for motor phase rotation, an upper 0.6 ohm DMOS transistor for PWM control and CMOS and bipolar circuits for logic and signal processing. The IC is assembled in a 20-l... View full abstract»

    Designers of switched-mode power supplies (SMPS) are constantly looking for ways to make their products lighter and smaller. The movement towards higher frequencies (100 kHz or above) is aimed at reducing the size of the magnetics and associated components and hence it little more than a design technique for reducing size. Likewise, the search for power integrated circuits in SMPS is mainly govern... View full abstract»

    The automotive intelligent power market is diverse with load currents varying from 0.1 to 30 A and with requirements for high side drivers, low side drivers and bridges. To meet the needs of these applications TI (Texas Instruments) has at its disposal a range of technologies, namely, bipolar IC, BIDFET, multiepi and multidie. The relative features of each of these technologies is discussed showin... View full abstract»

    The introduction of power MOSFET technology provided the necessary impetus for including power functions-up to several amperes capability, with operating voltages up to 100 V-in the monolithic Si structure. This is the result of the MOSFETs superior Si utilisation over any other topography at the stated working voltage. Full circuit protection against overloads in voltage and current with the adde...
