STMicroelectronics SLLIMM™ Intelligent Power Modules (IPMs)

STMicroelectronics SLLIMM™ Intelligent Power Modules (IPMs) extend ST's appliance-control product range with a thermally efficient solution that simplifies design by combining application specific IGBTs and diodes, proprietary control functions, smart protections and extra optional features. Directly connected to the microcontroller, IPMs convert microcontroller output into the correct high-power waveform to drive the motor. One module can replace more than 30 discrete components, thereby increasing reliability while reducing size and cost.

Features

  • 600V, 3-phase IGBT inverter bridge including gate-driving control ICs and freewheeling diodes
  • Short-circuit protected IGBTs
  • DBC fully-isolated package for enhanced thermal behavior
  • Smart shutdown function
  • Comparator for fault protection against overcurrent and short circuits
  • Op-amps for advanced current sensing
  • Integrated bootstrap diode
  • Small form factor
  • Easy to drive through microcontroller
  • High efficiency and reliability
  • Very low Rth
  • Reduced component count, cost-saving solution
  • Optimized layout
  • PCB space reduction (compact design)
  • 4.7kΩ NTC for temperature control
  • Lower failure rate (fewer components and solder joints)
  • Easy sensorless field-oriented control (FOC)

Applications

  • Programmable logic controllers (PLCs) 
  • Fail safe systems 
  • Designed for 24V bus 
  • 3-phase inverters for motor drives up to 2 kW
  • Home appliances: washing machines, air conditioners, dryers
