Nuvoton – Extreme space-saving MOSFETs for protection circuits and more

Through the acquisition of Panasonic’s semiconductor products, Nuvoton has also expanded its offering to include very space-saving MOSFETs.

These products are available exclusively in Chip-Scale-Package (CSP) and thus offer several advantages with extremely space-saving sizes at the same time:

• Almost the entire area of the MOSFET is its active area, this leads to a significantly lower R_DSON in comparison – typical 1.1mOhm at these products
• Monolithic design: Since the MOSFET is not made of DIE, bond wires, package, PIN material, etc. as in classical designs, the probability of failure is much lower. In Nuvoton’s CSP MOSFETs a current failure statistic of 0ppm is achieved.
• Another advantage of the monolithic design is the better heat distribution, which results in a 14% lower thermal resistance.
• Due to the small dimensions and the monolithic design the parasitic inductances are reduced to 0.01nH.

Designers can choose from over 20 types of dual N-channel FETs for V_SS=12V, 16 for V_SS=20-24V and one for V_SS=30V, 3 standard N and P types each for V_DS=12V and 10 derivatives each with AEC-Q101 qualification for use at V_DS=40-60V.

Typical application of the dual-channel FETs is the protection of Li-ion batteries in applications where space is limited, such as hearing aids, wireless in-ear headphones, e-cigarettes, smartphones/watches.

The above mentioned automotive derivatives find their application in the field of drivers for small loudspeakers for alerts as well as driving laser diodes for modern distance warning & monitoring systems like LiDAR.
