TOKYO— Toshiba Electronic Devices & Storage Corporation ("Toshiba") has released a 12V, common-drain N-channel MOSFET “SSM6N951L” for the battery protection circuits in lithium-ion battery packs for mobile devices. Shipments start today.
Battery protection circuits in lithium-ion battery packs are required to feature extremely low resistance that reduces heat dissipation during charging and discharging, along with high density and high redundancy that improves the safety of the protection circuit itself. Achieving this requires MOSFETs that are small and thin, with very low On-resistance.
Toshiba has developed a dedicated micro process technology that excels in low On-resistance characteristics to meet emerging requirements such as quick charging. Applying this in SSM6N951L contributes to realizing a longer battery operating life by securing lower standby power consumption, due to low gate-source leakage current characteristics, along with lower power dissipation realized by industry-leading low On-resistance characteristics.
Housed in a very small, thin chip scale package (CSP) (2.14x1.67mm t: 0.11mm (typ.)), the new MOSFET can be used in the limited, narrow mounting spaces characteristic of battery packs.
Toshiba will continue to develop products that are useful for such applications.
