STMicroelectronics SLLIMM-nano 2nd series intelligent power modules

Click2Contact

STMicroelectronics has expanded its intelligent power module portfolio with the SLLIMM-nano 2nd series, adding higher power levels and package options that are suited to increasing the efficiency and reducing cost. The SLLIMM-nano devices suit compressors, pumps and fans in domestic appliances and any low-power motors working up to 20 kHz in hard-switching circuits in an application power range up to 200 W.

The devices integrate three half-bridge, high-voltage gate drivers; six IGBTs; six fast and ultrasoft freewheeling recovery diodes; and low-voltage input logic that allow the devices to implement the complete interface between a low-power microcontroller and a mains-powered three-phase electric motor. The design of the embedded IGBTs and the freewheeling diodes is tailored to offer a trade-off between switching and conduction losses for low-power brushless DC motor applications, resulting in high efficiency and low electromagnetic interference.

Other features include: a 3–5 A current rating at 25°C, with 600 V breakdown voltage; mounted slot package options; an integrated bootstrap diode; 150°C maximum operating junction temperature; an integrated op amp and comparator; separate open emitter outputs; an NTC for temperature monitoring; smart shutdown function; inline and zig-zag lead options for maximum layout flexibility; and 1500 V_rms minimum isolation.
