MALVERN, PA -- (Marketwire) -- 10/16/09 -- Vishay Intertechnology, Inc. (NYSE: VSH) today
released two MICRO FOOT® power MOSFETs with maximum dimensions of 1 mm by
1 mm by 0.548 mm, which sets a new milestone as the smallest chipscale
power MOSFETs yet.
The 20-V p-channel Si8461DB and Si8465DB will be used for load switch,
battery switch, and charger switch applications in a wide range of portable
devices, where their small size and height will help reduce the space
occupied by power management circuitry and/or enable more functionality.
Compared to the next smallest chipscale power MOSFET on the market, the
1-mm by 1-mm by 0.548-mm MICRO FOOT has a 9 % smaller footprint.
On-resistance for the Si8461DB is 0.1 ohm at a 4.5-V gate drive, which
represents a tenfold improvement over non-chipscale devices with similar
footprint dimensions and thus provides a significant opportunity to
conserve battery energy in portable devices. In addition to the 4.5-V
rating, the Si8461DB is specified for maximum on-resistance values at 2.5
V, 1.8 V, and 1.5 V, which aligns the device with the smaller input signals
common in portable systems. For applications requiring higher input
voltages such as charger switches, the Si8465DB has a gate-to-source
voltage of 12 V; on-resistance is 0.104 ohms at a 4.5-V gate drive and
0.148 ohms at 2.5 V.
Samples and production quantities of the Si8461DB and Si8465DB are
available now, with lead times of 10 to 12 weeks for larger orders. Follow
