Vishay recently introduced new 12 V and 20 V n-channel and p-channel TrenchFET power MOSFETs with very low on-resistance in the 0,8 x 0,8 x 0,4 mm MICRO FOOT chip-scale package.
The new devices can be used for battery or load switching in power management applications for portable electronics. In addition to low conduction losses, the devices’ low on-resistance also means a lower voltage drop across the load switch to prevent unwanted under-voltage lockout.
The MOSFETs are built on an ultra-high density technology that uses self-aligning process techniques to pack one billion transistor cells into each square inch of silicon. When combined with MICRO FOOT’s packageless CSP technology, Vishay asserts that this provides the lowest on-resistance possible for a given outline area.
For n-channel devices, the result is a 43 mΩ maximum on-resistance at a 4,5 V gate drive for the 12 V Si8806DB. When a 20 V rating is needed, the Si8812DB offers a maximum on-resistance of 59 mΩ. The n-channel devices are optimal for high-speed switching applications with fast turn-on/off times of <100 ns, such as DC-DC boost converter applications.
The -20 V p-channel Si8817DB and Si8489EDB are optimised for buck converter applications. With 76 mΩ maximum on-resistance at a 4,5 V gate drive, the smaller 0,8 x 0,8 x 0,4 mm Si8817DB will be used for applications where space is even more critical than on-resistance. The 1 x 1 mm Si8489EDB will be used when the lower maximum on-resistance of 54 mΩ at 4,5 V is more critical.
The Si8489EDB provides 2500 V typical ESD protection. In addition, the Si8817DB offers on-resistance ratings down to 1,5 V, allowing the device to work with the lower-voltage gate drives and lower bus voltages common in handheld devices, saving the space and cost of level-shifting circuitry.
