STMicroelectronics SLLIMM Nano Modules for FOC Motor Control
STMicroelectronics’ SLLIMM nano Modules are compact and highly integrated modules that reduce losses and noise, simplify design, and increase reliability in home appliances and other motor control applications.
SLLIMM stands for small, low-loss, intelligent molded module. SLLIMM nano modules integrate 6 power switches, which can be Planar IGBTs, TFS IGBTs, MOSFETs, or Superjunction MOSFETs, as well as diodes. They also have built-in drivers that make them easy to control using an MCU. The modules include undervoltage lockout and overcurrent protection as well as temperature control thanks to the integrated NTC thermistor.
SLLIMM nano modules are available with an optional op-amp that can be used for current sensing and is ideal for applications using FOC motor control methods. The high level of integration in the modules reduces losses, EMI, BOM cost, and design complexity while simultaneously improving reliability and increasing power density.
ST offers a variety of SLLIMM nano modules to address varying application requirements. These include the SLLIMM nano, nano 2nd series, and nano SMD, and options with breakdown voltage up to 600V and current ratings up to 8A at 25°C, addressing applications up to 500W. SLLIMM nano SMD modules have a surface mount package and support heatsink-free design for applications up to 80W.
Nano 2nd series modules have a thicker package to provide a 1.5kVrms isolation voltage, and they include slots for easy heatsink attachment. Through-hole package options offer dual-inline or zig-zag leads options that can be ordered with or without stand-offs.
