Siliconix Debuts Battery Protection Power MOSFETs

August 06, 2002 by Jeff Shepard

Siliconix Inc. (Santa Clara, CA), a subsidiary of Vishay Intertechnology Inc., announced five new n-channel TrenchFET power MOSFETs aimed at battery-protection applications in one- and two-cell, lithium-ion and lithium-polymer battery packs and circuitry, the Si8900EDB, Si8902EDB, Si6876EDQ, Si6880EDQ and Si7902EDN. All five MOSFETs are rated for operation over a

temperature range of -55 to +150 degrees C.

The bi-directional, 20V MICRO FOOT Si8900EDB chip-scale power MOSFET features an on-resistance of just 24 milliohms at a 4.5V gate drive, and an average footprint area of 8.07mm². The Si8902EDB features an on-resistance of 45 milliohms at a 4.5V gate drive in an average footprint area of 3.68mm². Both devices feature a profile of just 0.62mm and provide 4,000V of ESD protection.

The bi-directional, 30V MICRO FOOT Si6876EDQ power MOSFET offers a low on-resistance of 30 milliohms at a 4.5V gate drive in a TSSOP-8 package for applications such as wall adapters. The 20V Si6880EDQ provides an

on-resistance of 18 milliohms at a 4.5V gate drive and is specified for operation down to 1.8V. It is available in the TSSOP-8 package. Both devices feature an ESD protection of 4,000V.

The 30V Si7902EDN dual common-drain power MOSFET is available in a PowerPAK 1212-8 package with a low profile of just 1.07mm and a footprint area of just 10.56mm², about half the size of the TSSOP-8. The Si7902EDN features an on-resistance value of 28 milliohms at a 4.5V gate drive and 3,000V of ESD protection.

Samples and production quantities of the Si8900EDB, Si8902EDB, Si6876EDQ, Si6880EDQ and Si7902EDN are available now, with lead times of 12 weeks for larger orders. Pricing for US delivery in 100,000-piece quantities ranges from $0.60 to $1.15.
