SLLIMM™ Small Low-Loss Intelligent Molded Module Simple, Compact, and Cool solution for motor drive up to 2kW Microelectronics SLLIMM™ Main features and integrated functions ● 600 V, 10 - 20 A ratings ● 3-phase IGBT inverter bridge including: – six low-loss and short-circuit protected IGBTs – six low forward voltage drop and soft recovery freewheeling diodes ● three control ICs for gate driving and protection including: – smart shutdown function – comparator for fault protection against overcurrent and short-circuit – op amps for advanced current sensing – three integrated bootstrap diodes – interlocking function – undervoltage lockout Main Applications • Washing machine • Dish washers • Refrigerators • Air conditioning compressor drives • Sewing machines • Pumps • Fans • Tools • Low power industrial applications • Rehabilitation and fitness applications 2 SLLIMM nomenclature Technical literature available: • Datasheets already published in st.com • Application Note AN3338 • Dedicated technical note TN0107 for mounting instructions published in st.com SLLIMM Line up Tj=from -40ºC to 150ºC Special features and protections • Shutdown pin (/SD) for an efficient connection with micro-controller • Embedded Op amps for advanced current sensing The IPM op-amp is completely uncommitted so a large amount of amplifier configurations can be implemented by the application designer. An example of amplifying network is figure below. Typically low tolerance resistors are used, if high accuracy is required in the conditioning of analog signals. • Embedded Comparator input (CIN) for Smart shut down The comparator non-inverting input (CIN) can be connected to an external shunt resistor in order to implement a simple over-current protection function. JUST IN 200 ns when the comparator triggers, the device is set in shutdown state and both its outputs are set to low level leading the half-bridge in tri-state The time delay between the fault and the outputs turn-off is no more dependent on the RC values of the external network connected to the shutdown pin. This feature is based on an innovative patented circuitry which provides an intelligent fault management operation and greatly reduces the protection intervention delay independently on the protection time duration which can be set as desired by the device user • Interlocking Function To Avoid any fault or mistake that can compromise the inverter leg due to the overlapping of the input signal • Integrated bootstrap diodes Component cost saving Easy layout • Overtemperature protection Negative temperature coefficient (NTC) thermistor for an easy overtemperature protection, in the case of slow case temperature drift or just for the temperature measurements, sending this information to the microcontroller in real-time DBC & Vacuum soldering process Part number PCB layer for gate drivers and SMD DBC technology for power stage for better heat dissipation (direct bonded copper has two layers of copper that are directly bonded onto an aluminum-oxide (Al2O3) ceramic base) RTH (°C/W) STGIPS10K60A 3.8 STGIPS14K60 3 STGIPL14K60 2.4 STGIPS20K60 2.8 ST’s dual in line (DIP) molded packages use A vacuum soldering process is used to avoid any gas inclusion (voids) during the soldering process that could cause potential hot spots. It results in a further increase in the reliability of ST’s IPMs due to the improved thermal and electrical conductivity. DBC + Vacuum soldering process = low thermal resistance values stability in thermal cycling.
