Toshiba Launches 30V N-Channel Common-Drain MOSFET Suitable for Devices with USB and for Protecting Battery Packs
Realizing a bi-directional switch with a low drain-source on-resistance (RDS(ON)) has required two MOSFETs, either 3.3×3.3mm or 2×2 mm, with low RDS(ON). Toshiba’s new product uses a new, small, thin package TCSPAG-341501 (3.37mm×1.47mm (typ.), t=0.11mm (typ.)), and features low source-source on-resistance (RSS(ON)) of 9.9mΩ (typ.) in a single package common-drain configuration
USB Power Delivery (USB PD) that supports a power supply ranging 15W (5V / 3A) to a maximum of 240W (48V / 5A) was developed for devices requiring high power supply. USB PD 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, so that both sides can supply and receive power. 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 today released a reference design for a power multiplexer circuit (using common-drain MOSFETs) based on this product combination. Use of the reference design will help to reduce product design and development times.
Toshiba will continue to expand its product line-up and improve characteristics, to raise design flexibility.
