optimized to simplify circuit-board layout. A wide range of domestic and industrial appliances, such as small fans, roller shutters, refrigerator compressors, dishwashers, draining and recirculation pumps, and general low-power motor drives, can benefit from the small size, high energy efficiency, excellent reliability, and safe, low- noise performance of ST’s new IPMs. Extra features integrated alongside the gate driver and 500V MOSFET or 600V IGBT/freewheel-diode array include an uncommitted operational amplifier and a comparator that let designers implement advanced current sensing and over- current protection with minimal external components. Smart shutdown with high-speed fault detection, interlocking, and under-voltage lockout are all built-in, and integrated bootstrap diodes simplify powering the module’s gate- control circuitry. The new SLLIMM -nano power modules, comprising the STIPNS1M50T-H, STIPNS2M50T-H, STIPNS2M50-H, STGIPNS3H60T-H, and STGIPNS3HD60-H, provide a choice of 1A, 2A, or 3A current rating (at 25°C). All are packaged as NSDIP-26L fully-molded dual-inline surface- mount devices. Engineering samples are available now and volume production will commence in Q4 2017. Pricing starts at $5 for 1000 pieces of the STIPNS1M50T-H.

ceramic capacitors and no inductors) make the LTC3246 ideal for noise-sensitive space constrained automotive applications such as ECU/CAN transceiver supplies, as well as industrial housekeeping supplies and efficient low power 12V to 5V conversion. The LTC3246’s switched capacitor architecture with inherent soft switching provides lower radiated noise and EMI compared with conventional switching regulators. Timing control for the reset timeout and the windowed watchdog timeout can be adjusted using external capacitors on the RT and WT pins, or fixed internally via pin strapping. The accurate threshold of the reset input can be used for additional supply monitoring, or can be configured as a pushbutton reset. Other features include stability with ceramic capacitors, foldback current limiting to prevent excessive current flow during start-up, plus short-circuit and thermal protection

Surface-Mount Intelligent Low-Power Modules from STMicroelectronics Save Space in Energy-Efficient Motor Drives STMicroelectronics has added five space-saving surface- mount intelligent power modules (IPM) to its SLLIMM™- nano family, giving the choice of IGBT or MOSFET outputs for in-motor or other space-constrained drives all the way from very low power ratings up to 100W. The new modules deliver high conduction and switching efficiency, especially in hard-switching circuits at frequencies up to 20kHz. The integrated gate-driver circuitry is engineered to minimize electromagnetic emissions (EMI) by managing switching voltage and current slopes (dV/dt, di/dt). The thermally efficient package enhances reliability and allows heatsink-free design, while 2.7mm creepage and 2.0mm clearance ensure safety isolation within the compact dual-inline SMD footprint. The module pin configuration is

Analog Devices Lays Foundation for 4G to 5G Migration with Expanded RadioVerse™ Wireless Technology and Design Ecosystem (ADI) today announced the latest update to its award-winning RadioVerse™ technology and design ecosystem, which simplifies and accelerates radio development for wireless carriers and telecommunications equipment manufacturers as they transition their cellular base stations from 4G to 5G networks.
