Infineon Technologies Corp. (San Jose, CA) introduced the first devices in a new generation of high-side, High-Current PROFET intelligent power switches. The new devices offer high thermal ratings and an Rds(on) of 2.5milliohms, and are capable of handling continuous amp load currents of 100A or more (450A inrush), according to Infineon.Like Infineon's recently announced miniPROFETs, […]
Cherry Semiconductor Corp. (East Greenwich, RI) introduced three new vacuum fluorescent display (VFD) driver ICs designed to eliminate excess circuitry in automotive instrumentation systems where the system microprocessor has sufficient pins to control driver ICs. The CS1084, CS1085 and CS1086 each contain a shift register, transparent data latches, a metal-mask read-only memory (ROM) and anode- […]
Zetex Inc. (Commack, NY) introduced the new ZHCS400 high-current Schottky diode in the miniature SOD323 surface-mount package. The new diode will support...
Mitel Semiconductor (formerly GTEC Plessey Semiconductor, Lincoln, UK) has developed a 1.2-kV trench IGBT with an on-resistance of 1.1V for non-irradiated devices and 2.1V for irradiated devices. These 25A punch-through devices were fabricated based on stripe and hexagonal geometries. The trench width versus trench spacing of these devices was optimized to obtain minimum on-resistance without […]
The new LM2685 from National Semiconductor Corp. (Santa Clara, CA) is a dual-output switched capacitor regulator that integrates a switched capacitor doubler, a low dropout (LDO) regulator and a switched capacitor inverter in a low profile TSSOP-14 package. The LM2685 provides a dual output (+5V regulated and -5V unregulated) power supply by using switched capacitor […]
