This allows to operate the electronics in domestic appliances at a higher voltage, provides a large safety margin against supply voltage fluctuations in unregulated supply networks and allows to drive actors requiring a higher voltage directly from the IC. For the ASIC design of applications at higher voltage on the supply line as well as on input or output signals, a variety of circuit blocks is available; e.g. linear regulators, output drivers and various comparators and operational amplifiers.  Because high voltage transistors can be integrated, components that needed to be mounted as discretes on the PCB with conventional ASICs can now be saved.Both NPN and PNP transistors are available with a collector-to-emitter breakdown voltage, base open, of more than 135V, thus permitting to avoid awkward and error-prone concepts like cascodes or stacked switches. Since high-voltage components can be combined seamlessly with low-voltage components, a high integration density can be achieved. The heat to be dissipated can be kept low, as besides the high voltage cells also components with ultra low power consumption are available, such as gates.For example, an H-bridge which is part of the ASIC can drive a piezo actor with voltages up to ±120V. The operational amplifier can sense signals up to close to the supply voltage. PREMA´s application team looks forward to meeting interested customers to discuss their ASIC ideas and requirements during the embedded world 2005 from February 22 till 24 in Nuremberg, in hall 12.0 booth 466.
