L639x: the MOSFET and IGBT smartDRIVE™ solution STMicroelectronics A new approach in 600 V IGBT and MOSFET gate drivers, delivers value to your application through sensible integration Most applications are increasingly driven by performance, cost and efficiency requirements. Based on its field proven highvoltage (600 V) IC technology, STMicroelectronics’ (ST) smartDRIVE L639x family embeds a rich set of functionalities, including an integrated comparator for protection, an op amp suitable for current sensing (especially for field-oriented motor drive application), and an integrated bootstrap diode. Key features Half bridge configuration with up to 600 V ratings 270/-430 mA gate drive current capability Rich logic interface with full compatibility from 3.3 V CMOS yet 15 V tolerant On chip op amp for current sensing Comparator for protection with fast internal loop Integrated bootstrap diode Adjustable dead time SO/DIP 14 and SO/DIP 16 package Main applications Home appliances: washing machines, dish washers, induction cooking ranges etc. HVAC systems Industrial drives, field-oriented and sensor-less control Pumps, fans, DC motors Lighting applications Plasma display panels LCD backlight section Power supplies This is all meant to help reduce part count and the cost in your power conversion application, whether in a motor control, an electronic lighting ballast or a switch mode power supply design. www.st.com and amplification functionalities found in each of the motor control applications (especially those field oriented), can be accomplished through the integrated, fully accessible op amp. An integrated bootstrap diode completes a suite designed to enable a considerable board level part count A sensible integration path has brought a number of board level must have functionalities on chip. An integrated comparator is coupled with a fast internal shutdown loop to implement an effective fault management strategy (patented). Protection features are completed with an integrated voltage monitor (under voltage lock out) on both ground referenced and floating supply. Using the integrated, externally set, dead time generator, shoot through in the bridge leg can be avoided in all conditions. This means board layout can be easily optimized while application robustness is greatly enhanced. In addition, current sensing carefully sized for applications up to 1.5 kW. Finally, knowing how noisy and harsh a typical power conversion application might be, critical attention has been given to the level shifting and signal decoding circuitry, thus enabling a full compatibility with fast transients generating high dV/dt, up to 50 V/ ns on the half bridge mid point. The family comprises a variety of different implementations of the basic building blocks, creating a differentiated offer able to cope with specific requirements as found in a variety of power conversion applications. Simplification opportunities can also be found at the logic interface with the application microcontroller. Here are found separate out-of-phase, highside and low-side and a shutdown input - driving off both high- and low-side power switches - all 3.3 V CMOS compatible but tolerant up to 15 V.
