P-Channel device, industry’s first in this package size

Vishay Intertechnology has announced what it claims is the first p-channel power mosfet in the 'industry's smallest' 0.8 x 0.8mm chipscale package.

According to Vishay, it features the first n- and p-channel devices to offer on resistance ratings down to 1.2V in this package size. The company says the 8V 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, but offer comparable on resistance. Both devices are designed for load switching in handheld devices such as smart phones, tablets, portable media players and mobile computing devices. The mosfets have a 0.357mm profile and feature low on resistance at 1.5V and on resistance specified with a gate drive of 1.2V. This, says Vishay, 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.
