Toshiba launches 30V N-channel common-drain MOSFET for devices with USB and battery pack protection

【Lansheng Technology News】November 7, 2023 -Toshiba ElectronicComponents and Storage Co., Ltd. announced today the launch of "SSM10N961L" low on-resistance 30V N-channel common-drain MOSFET, suitable for devices with USB and Battery pack protection. This product starts shipping in bulk today.

Up to now,Toshiba'sN-channel common-drain MOSFET product line focuses on 12V products, mainly used for the protection of smartphone lithium-ion battery packs. The release of 30V products provides a wider range of options for applications with voltages higher than 12V, such as load switching for power lines in USB charging devices and protection of lithium-ion battery packs in laptops and tablets.

Implementing a bidirectional switch with low drain-source on-resistance (RDS(ON)) requires two MOSFETs with low RDS(ON), measuring 3.3mm × 3.3mm or 2mm × 2mm. Toshiba's new product uses a small and thin new package TCSPAG-341501 (3.37mm × 1.47mm (typ.), thickness = 0.11mm (typ.)), and carries a resistance value of 9.9mΩ in a single package common drain structure. (Typical) source-to-source on-resistance (RSS(ON)).

USB PD (USB Power Delivery) is specially developed for devices that require high power supply and can provide power from 15W (5V/3A) to a maximum of 240W (48V/5A). USB PD has a role exchange function and supports the exchange of the power side and the receiving side. It requires the USB charging device to be capable of bidirectional power supply so that it can support power transmission and power reception at the same time. This new product is an N-channel common-drain MOSFET that supports bidirectional power supply and has a small surface mount area.

Combining this product with driver ICs in Toshiba's TCK42xG series can form a load switch circuit with backflow prevention or a power multiplexer that can switch between make-before-break (MBB) and break-before-make (BBM) operations. device circuit. Based on this product combination, Toshiba today released a reference design for power multiplexer circuits (using common-drain MOSFETs). Using this reference design can help reduce product design and development time.
