1 / 60 page ![]() September 2012 Doc ID 022726 Rev 2 1/60 AN4043 Application note SLLIMM™-nano small low-loss intelligent molded module By Carmelo Parisi and Giovanni Tomasello Introduction In recent years the variable speed motor control market has required high performance solutions able to satisfy the increasing energy saving requirements, compactness, reliability, and system costs in home appliances, such as dish washers, refrigerator compressors, air conditioning fans, draining and recirculation pumps, and in low power industrial applications, such as small fans, pumps and tools, etc. To meet these market needs, STMicroelectronics has developed a new family of very compact, high efficiency, dual-in-line intelligent power modules, with optional extra features, called small low-loss intelligent molded module nano (SLLIMM™-nano). The SLLIMM-nano product family combines optimized silicon chips, integrated in three main inverter blocks: ● power stage – six very fast IGBTs – six freewheeling diodes ● driving network – three high voltage gate drivers – three gate resistors – three bootstrap diodes ● protection and optional features – op amp for advanced current sensing – comparator for fault protection against overcurrent and short-circuit – smart shutdown function – dead time, interlocking function and undervoltage lockout. Thanks to its very good compactness, the fully isolated SLLIMM-nano package (NDIP) is the ideal solution for applications requiring reduced assembly space, without sacrificing thermal performance and reliability. Compared to discrete-based inverters, including power devices, and driver and protection circuits, the SLLIMM-nano family provides a high integrated level that means simplified circuit design, reduced component count, lower weight, and high reliability. The aim of this application note is to provide a detailed description of SLLIMM-nano products, providing guidelines to motor drive designers for an efficient, reliable, and fast design when using the new ST SLLIMM-nano family. www.st.com |
