Lineup expansion of small, low On-resistance common-drain MOSFET products helping battery-driven devices operate for longer periods of time : SSM10N954L
Product News 2021-04
Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched “SSM10N954L,” a common-drain 12 V N-channel MOSFET for battery protection circuits used for Lithium-ion (Li-ion) battery packs of mobile devices and other equipment to expand the lineup.
Li-ion battery packs use highly robust protection circuits to enhance safety. And it is also demanded to reduce heat generation during charging/discharging Li-ion battery. Such protection circuits require low power loss and high-density mounting, therefore, small and thin MOSFETs with low On-resistance are needed.
Similar to the previously released SSM6N951L, the new product uses its micro process and has further reduced its On-resistance. This allows the product to offer low power loss because of its industry-leading[1] low On-resistance characteristics. And by also featuring low standby power consumption because of its low leakage current from the gate (low gate-source leakage current), it helps batteries to operate for longer time. In addition, it uses the new package TCSPAC-153001 (1.49 mm x 2.98 mm, t : 0.11 mm (typ.)).
