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;
- 1500Vrms minimum isolation (no opto-coupler required);
- Low VCE(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.
