STMicroelectronics (ST) has added the new SLLIMM™-nano 2nd series to its intelligent power module portfolio. It is a product suitable for increasing efficiency and saving costs by providing higher levels of power and a new package.

It is suitable for all low-power motors operating up to 20kHz in hard-switching circuits of applications with a maximum power range of 200W, including compressors, pumps, and fans used in home appliances such as refrigerators and washing machines.

The SLLIMM nano device is equipped with three half-bridge high-voltage gate drivers, six IGBTs, and six high-speed ultra-soft freewheeling recovery diodes, as well as low-voltage input logic that enables a perfect interface between a low-power microcontroller and a main-power three-phase electric motor.

The design of this integrated IGBT (Planar technology for 3A and dedicated TFS (Trench-gate Field Stop) technology for the 5A version) and freewheeling diode is custom-designed to strike the best balance between switching and conduction losses in low-power BLDC (Brushless DC) motor applications, resulting in higher efficiency and reduced electromagnetic interference.
