Intelligent power modules enable greener appliances

These devices build on the success of ST's proven SLLIMM (Small Low-Loss Intelligent Molded Module) family of dual-in-line modules. These provide a direct connection between a low-voltage MCU and a mains-powered electric motor, replacing up to 10 active components. The SLLIMM 2nd series offers higher performance, increased collector current range and additional package-technology options that can further reduce the cost of the application by enabling the use of smaller heatsinks.

The SLLIMM 2nd series features a new internal configuration with only two drivers - one high-side driver and one low-side driver - and dedicated trench-gate field-stop IGBTs, resulting in the industry's best compromise between conduction and switching losses, along with outstanding robustness and EMI behaviour.

Key technical features include:

• Up to 35A maximum collector current at 25°C;
• Fully molded and DBC (Direct Bond Copper) dual-in-line (38x24mm²) pin-compatible package options;
• Industry's lowest thermal resistance for the DBC package versions;
• Internal bootstrap diode to reduce BOM and simplify layout;
• 175°C maximum operating junction temperature;
• 1500V_rms minimum isolation (no opto-coupler required);
• Low V_CE(sat);
• Low EMI;
• Separate open emitter outputs to simplify PCB routing for single- and three-phase applications;
• Built-in temperature sensor and negative temperature coefficient option;
• Comparator for fault protection;
• Shutdown input/fault detection output; and
• Two pin-out and two lead-frame options.

Most of the devices in ST’s SLLIMM 2nd series are in full production, with pricing starting at $9.50 in 1,000 unit quantities.
