New SCALE-2 Plug-and-Play Gate Drivers from Power Integrations Suit a Wide Range of IGBT Modules

Power Integrations (Nasdaq:POWI), the leader in IGBT and MOSFET driver technology for medium- and high-voltage inverter applications, today introduced the 1SP0350V SCALE™-2 single-channel +15/-10 V plug-and-play gate driver. Optimally suited to high-reliability applications in the HVDC and railway industries, the 1SP0350 gate driver reliably and safely drives 4500 V Press-Pack IGBTs and IEGTs as well as other IGBT and IEGT form factors. Based on Power Integrations’ widely used SCALE™-2 chipset, the new driver is equipped with Dynamic Advanced Active Clamping (DAAC), short-circuit protection, a built in DC-DC converter, regulated turn-on gate drive voltage, DC-DC overload monitoring and supply voltage monitoring.

Brad® M12 Power F-Coded Connectors Deliver 16.0A Current Carrying Capacity

New Cordsets and Receptacles Enable Factory Automation

Molex, LLC has introduced Brad® M12 Power F-Coded cordsets and receptacles, featuring an industry-leading current carrying capacity of up to 16.0A per pin with a blind-mate key design. While the products were developed to meet the growing power requirements of motors, solenoid-operated valves, actuation equipment and 24V DC auxiliary power systems in automation control systems, they are also well suited for LED lighting and commercial vehicle applications.

“The new Brad M12 Power interconnect system offers key advantages over existing connector interfaces that are larger and more expensive, such as M23 and MIL-C-5015 devices,” said Randy Brant, product manager, Molex. “Also, the connector’s F-Coding mating interface is expected to be adopted by the IEC Standard 61076-2-111 and has been submitted for ANSI/EIA acceptance, which will allow for an open industry connector standard. This will increase adoption among a wide array of platforms and manufacturers.”

60V Synchronous Buck Battery Charger Includes Lead-Acid & Li-Ion Charge Algorithms for up to 20A Charge Current

Linear Technology Corporation introduces the LTC4013, a highly integrated, high voltage multi-chemistry synchronous step-down battery charger controller. With a wide input voltage range that spans up to 60V, the LTC4013 uses temperature-compensated 3- and 4-stage charge algorithms to efficiently charge 12V and 24V lead-acid batteries. Alternatively, the LTC4013 will charge a multicell Lithium-based battery stack with float voltages near to the input supply. Mode pins define the float voltage and charge algorithm. Charge current is precision regulated to ±5% and programmable with a single resistor up to 20A (depending on the selection of external components). The LTC4013 features user-adjustable maximum power point tracking (MPPT) circuitry that enables simple power optimization in the case of power-limited sources such as solar panels. The MPPT open-circuit method corrects for panel temperature changes without the inconvenience of adding a solar panel temperature sensor. Applications include portable medical instruments, monitoring equipment, battery backup systems, industrial handhelds, industrial lighting, military equipment, ruggedized notebooks/tablet computers, plus remote powered communication and telemetry systems.

3 Steps Electrical Engineers Should Take to Obtain the Best Electronic BoM Costs

To stay competitive in today’s extremely tough markets, electrical engineers have to not only be technically adept at designing in components that give their products a competitive edge, but they also have to know the best practices in assuring that the Bill of Material (BoM) costs are as low as possible.  As the electronic component BoM cost usually represents the single largest cost element of an end-product, being good at controlling these costs can give companies in saturated markets a competitive edge. 

The field applications engineers at SemiElectronics have come up with the 3 top items that engineers should pay attention to during design process and beyond to leverage the best BoM costs possible.
