Vishay Siliconix MICRO FOOT(R) N-Channel and P-Channel Power MOSFETs Are Industry's First to Feature On-Resistance Ratings Down to 1.2 V in Industry's Smallest Chipscale Package
P-Channel Device Is Industry's First in This Package Size
(firmenpresse) - MALVERN, PA -- (Marketwire) -- 10/20/11 -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the industry's first p-channel power MOSFET in the industry's smallest 0.8 mm by 0.8 mm chipscale package, in addition to the first n- and p-channel devices to offer on-resistance ratings down to 1.2 V in this package size. The 8 V n-channel Si8802DB and p-channel Si8805EDB TrenchFET® power MOSFETs in the MICRO FOOT® package occupy up to 36 % less board space than the next smallest chipscale devices, yet offer comparable -- and even lower -- on resistance.
The Si8802DB and Si8805EDB will be used for load switching in handheld devices including smart phones, tablets, portable media players, and mobile computing devices. The MOSFETs' ultra-thin 0.357 mm profile saves valuable board space in these applications -- enabling smaller, slimmer mobile products.
The devices released today feature low on-resistance at 1.5 V with the added benefit of on-resistance specified with a gate drive of only 1.2 V. This simplifies designs by allowing the MOSFETs to work with the low-voltage power rails common in handheld devices, eliminating an extra resistor and voltage source for p-channel load switching, and providing longer battery operation between charges in n-channel load switching.
The n-channel Si8802DB offers on-resistance of 54 milliohms at 4.5 V, 60 milliohms at 2.5 V, 68 milliohms at 1.8 V, 86 milliohms at 1.5 V, and 135 milliohms at 1.2 V. While the device's package outline is 36 % smaller than the next smallest device, its on-resistance values at 1.8 V and 1.5 V are 5.5 % and 7.5 % lower, respectively.
The p-channel Si8805EDB features on-resistance of 68 milliohms at 4.5 V, 88 milliohms at 2.5 V, 155 milliohms at 1.5 V, and 290 milliohms at 1.2 V. While occupying 29 % less board space than the next smallest p-channel device, its on-resistance values at 4.5 V and 2.5 V are still 17 % and 8 % lower, respectively. The lower on-resistance of the Si8802DB and Si8805EDB minimize voltage drops across the load switch to prevent unwanted under-voltage lockout.
The devices are halogen-free in accordance with the IEC 61249-2-21 definition and compliant to RoHS Directive 2002/95/EC. The Si8805EDB offers ESD protection of 1500 V.
Samples and production quantities of the new Si8802DB and Si8805EDB TrenchFET power MOSFET are available now, with lead times of 12 to 14 weeks for larger orders. Follow Vishay Siliconix TrenchFET at .
