Power MOSFET Delivers Smallest Size and On-Resistance for Type
Provided in a MICRO FOOT chipscale package with a 0.59 mm profile and a footprint of 1.5 mm × 1 mm, the Vishay Siliconix Si8441DB 20-V p-channel TrenchFET power MOSFET is presented as having the industry’s lowest profile for this device type. It is also presented as having the lowest on-resistance for such devices with a range from 0.600O at 1.2V VGS to 0.080O at 4.5V VGS with a maximum gate-source voltage of +/- 5V. Typical applications for the power MOSFET will include load switching and battery protection in portable devices such as cell phones, PDAs, digital cameras, MP3 players, and smart phones.
