Fully integrated 12-V power breaker disconnects faulty loads
STMicroelectronics’ STPW12 programmable electronic power breaker provides a convenient, integrated solution for quickly and safely disconnecting a faulty load from a 12V bus. Inserted between the power rail and the load, the STPW12 contains a low-resistance (50mΩ) power switch and precision circuitry for sensing the load power. If the user-programmed limit is exceeded, the switch turns off […]
ST Microelectronics and Leti collaborate to develop and industrialize advanced power GaN-on-Si architectures
ST Microelectronics and Leti, a research institute of CEA Tech, today announced their cooperation to industrialize GaN (Gallium Nitride)-on-Silicon technologies for power switching devices. This power GaN-on-Si technology will enable ST to address high-efficiency, high-power applications, including automotive on-board chargers for hybrid and electric vehicles, wireless charging, and servers. The collaboration focuses on developing and […]
Low-side driver ICs for SMPS guard against false triggering of power MOSFETS
Every time a power MOSFET is switched on or off in a switched-mode power supply (SMPS), parasitic inductances cause ground shifts. This can lead to uncontrolled switching of gate driver ICs. In extreme cases, this results in electrical overloading of power MOSFETs and malfunctioning of the SMPS. To solve this problem, Infineon Technologies offers the […]
650V SiC Schottky rectifiers handle energy sensitive, high frequency applications
