Vishay Siliconix Si846xDB MICRO FOOT® Power MOSFETs
Vishay Siliconix 20-V p-channel Si8461DB and Si8465DB MICRO FOOT® power MOSFETs are the smallest chipscale power MOSFETs on the market (1-mm by 1-mm by 0.548-mm). These Vishay Siliconix MICRO FOOT power MOSFETs
can be used for load switch, battery switch, and charger switch
applications in a wide range of portable devices. The small size and
height of the Si8461DB and Si8465DB reduce the space occupied by power management circuitry and enable more functionality. These Vishay Siliconix MICRO FOOT power MOSFETs have a 9% smaller footprint than the next smallest chipscale power MOSFET on the market.
Vishay Siliconix Analog Switches and Multiplexers
Vishay Siliconix offers a broad range of high performance analog switches and multiplexers, including the quad SPST DG61xx switches that provide high frequency and improved on-resistance and charge injection for precision instrumentation applications. The Vishay Siliconix DG508 8-channel CMOS analog multiplexer provides an extended maximum voltage rating to 44V with rail-to-rail analog capability and can be operated in either a dual or single supply configuration. Vishay Siliconix DG41xx analog switches and multiplexers deliver faster, more accurate signal processing performance with lower power consumptions.Vishay Siliconix also provides the DG27xx low-voltage analog switches that target portable systems and feature on-resistance down to 0.25Ω and current handling up to 300mA for load switching.
Vishay Siliconix Power Management ICs
Vishay Siliconix power management ICs include new high-performance SiC769 integrated power stage devices with Gen III MOSFET and DrMOS-compliant gate driver IC and SiC413 / SiC417 synchronous buck regulators with integrated PWM controller and Gen III Trench MOSFETs. The Vishay Siliconix SiC769 integrated power stage IC is a power management device that enables Vcore switching at 1 MHz and can easily achieve greater than 90% efficiency in multi-phase, low output voltage solutions. The Vishay Siliconix SiC413 synchronous buck regulator is a microBUCK™ family power management device featuring integrated current sense, cycle by cycle over-current protection, and a built-in bootstrap diode. The SiC413 provides 4A continuous output current. The SiC417 synchronous buck regulator is a microBUCK power management device offering 10A continuous output current along with integrated configurable 150 mA LDO with bypass logic, integrated bootstrap diode, and temperature compensated current limit.
Vishay Siliconix TrenchFET® Gen III Power MOSFET
The Vishay Siliconix TrenchFET® Gen III Power MOSFET family offers the industry's lowest on-resistance and on-resistance times gate charge for a device with this voltage rating in the PowerPAK® SO-8, PowerPAK® 1212-8, and SO-8 package types. The Vishay Siliconix TrenchFet Gen III Power MOSFET improves greatly on the performance of the closest competing devices. The lower on-resistance and gate charge of the TrenchFet Gen III Power MOSFET translate into lower conduction and switching losses. Several devices in the TrenchFET family are also equipped with TurboFET™ technology, which won the EN-Genius award for Best Improvement in Power Devices. Vishay Siliconix TrenchFET devices are used as the low-side MOSFET in synchronous buck converters and in secondary synchronous rectification and OR-ing applications.
