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

 


【Lansheng Technology News】November 7, 2023 - Toshiba Electronic Components 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's N-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.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
