Toshiba Launches Small and Thin Common-Drain MOSFET
Toshiba has launched “SSM14N956L,” a 12V common-drain N-channel
MOSFET with a current rating of 20A, for use in battery protection circuits in
lithium-ion (Li-ion) battery packs, such as those for mobile devices. Shipments
start today.
Li-ion battery packs rely on highly robust protection circuits
to reduce heat generation while charging and discharging and to enhance safety.
These circuits must feature low power consumption and high-density packaging,
requiring MOSFETs that are small and thin and that deliver low On-resistance.
SSM14N956L uses Toshiba’s micro-process, as does the already
released SSM10N954L. This ensures both low power loss, due to industry-leading[1] low
On-resistance characteristics, and low standby power, realized by
industry-leading[1] low gate-source leakage current characteristics. These
qualities help to extend battery operating hours. The new product also uses a
new small, thin package, TCSPED-302701 (2.74mm x 3.0mm, t = 0.085mm (typ.)).
Toshiba will continue to develop MOSFET products for protection
circuits in devices powered by lithium-ion battery packs.
Applications
