Toshiba Unveils Low On-resistance 30v N-channel Common-drain MOSFET

KUALA LUMPUR, Nov 7 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched “SSM10N961L”, a low on-resistance, 30 volt (V) N-channel common-drain metal-oxide semiconductor field-effect transistor (MOSFET), suitable for devices with USB and for protecting battery packs.

According to Toshiba in a statement, the shipment has started, and until now Toshiba’s line-up of N-channel common-drain MOSFETs has focused on 12V products, mainly for use in protecting the lithium-ion battery packs of smartphones.

The release of a 30V product realises a wider selection of applications requiring voltages higher than 12V, such as load switching for the power lines of USB charging devices, and the protection of lithium-ion battery packs in laptop personal computers and tablets.

Toshiba’s new product uses a new, small, thin package TCSPAG-341501 and features low source-source on-resistance in a single package common-drain configuration.

USB Power Delivery that supports a power supply ranging 15 watt (W) to a maximum of 240W was developed for devices requiring high power supply. It specifies a role swap function for swapping the power supply and receiving side, and requires devices with USB charging to support bi-directional power supply.

The new product is an N-channel common-drain MOSFET that supports bi-directional power supply, and that has a small mounting area.

Combining the product with a driver IC in Toshiba’s TCK42xG series forms a load switching circuit with a backflow prevention function or a power multiplexer circuit that can switch operations between Make-Before-Break (MBB) and Break-Before-Make (BBM).

Toshiba has also released a reference design for a power multiplexer circuit (using common-drain MOSFETs) based on this product combination whereby use of the reference design will help to reduce product design and development times.

The company will continue to expand its product line-up and improve characteristics, to raise design flexibility.
