Toshiba Debuts N-ch MOSFET for Lithium-ion Battery Protection Circuits

Features Low ON-Resistance and Low Capacitance in a High Radiation Performance Package

IRVINE, Calif., July 25, 2013 — (PRNewswire) —   Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the launch of a semi-power N-ch MOSFET for lithium-ion battery protection circuits: the SSM3K324R.  Designed for notebook PC lithium-ion battery protection circuits, the SSM3K324R brings ON-resistance and low capacitance in a large capacity, high radiation performance package.

Although they are one of the fastest-growing segments of today's battery market, lithium-ion batteries are not without disadvantages.  Fragile by nature, they require protection circuits in order to operate safely.  Protection circuit modules limit the peak voltage of each cell during charge and prevent the cell voltage from dropping too low on discharge – as well as prevent accidental battery explosion.  Battery packs for notebook PCs are equipped with protection circuits that have the ability to detect a problem and blow an internal fuse before the packs are damaged.  Toshiba's new SSM3K324R blows the fuses in the case of such an event.

A successor to Toshiba's popular SSM3K316T, the SSM3K324R uses the latest UMOSVII-H process to enable a significant reduction in gate switch charge and on-state resistance (RDS(ON)), resulting in greater power efficiency.  Toshiba's new N-ch MOSFET is mounted on the SOT-23F package (2.9mm x 2.4mm), which offers superior radiation performance, and can be installed in the SOT-23 package land pattern.
