MALVERN, Pa.— April 14, 2011— Vishay Intertechnology, Inc. (NYSE: VSH) today released three new single and dual 2 A load switches designed for 1.1 V to 5.5 V operation. Offering low switch on-resistance at 1.2 V for increased efficiency, theSiP32411,SiP32413, andSiP32414feature a controlled soft turn-on slew rate of 150µs typical that limits the inrush current, providing a controlled smoother turn-on transition that minimizes switching noise.
TheSiP32411is a single switch available in both the 1.2 mm by 1.6 mm TDFN4 package and the SC70-6 package, while theSiP32413andSiP32414are dual switches available in the 2 mm x 2 mm TDFN8 package. The load switches released today guarantee low switch on-resistance of 66 mΩ at 1.2 V input (105 mΩ for theSiP32411in the SC70-6 package), with each switch supporting over 2 A of continuous current.
The space-savingSiP32411,SiP32413, andSiP32414feature a low-voltage control logic interface that eliminates the need for extra level shifting circuitry. The devices offer a low quiescent current of< 1µA when disabled and 6.7 µA at 1.2 V, allowing for longer on-times in battery-powered equipment. When disabled, the switches provide reverse blocking to prevent high current from flowing into the power source. TheSiP32411andSiP32414integrate output discharge switches that enable rapid turn-off of a load circuit when the switch is disabled.
The two load switches in theSiP32413feature reverse control logic. The device can easily be configured as a two-to-one power source, routing two power rails of different potentials to the common load point. TheSiP32414consists of two load switches of the same logic, and is ideal for loads with dual power rails.
TheSiP32411,SiP32413, andSiP32414will be used in USB, SIM, SDIO, POL, RF, and Wi-Fi module load applications in wireless modems and portable devices including, netbooks and notebook computers, cell phones, GPS products, digital cameras, and eBooks. The devices are compliant to RoHS Directive 2002/95/EC and halogen-free according to the IEC 61249-2-21 definition.
Samples of the new load switches are available now. Production quantities will be available in May, with lead times of 10 weeks for larger orders.
