Typical automotive power electronics applications for TO-LL packaged devices include battery management systems for electric and electric-hybrid vehicles, battery safety switches, start-stop systems, and motor drives and active rectifiers for electric power steering (EPS). Fairchild offers devices optimized for traditional 12V battery systems as well as solutions supporting new board-net architectures, such as 48V.

“Fairchild combines PowerTrench MOSFET technology with the current-carrying and thermally advantageous TO-LL package to deliver power switches with the industry’s lowest on-resistance,” said Heiner Gschloessl, Director of Fairchild’s Automotive Business Unit. “This combination provides designers of the most demanding automotive power applications with enhanced switching performance and reliability.”

Highest efficiency, small size, and economical system price

Measuring just 2.3 x 9.8 x 10.38 mm, the TO-LL package is approximately 30% smaller than the D2PAK (TO263) package and supports current handling capability of up to 300 A. The TO-LL is nearly half the height, making it ideal for many automotive applications where space is often at a premium.

Fairchild's leadless MOSFETs, combining the latest PowerTrench shielded gate trench technology with the TO-LL package, deliver exceptionally low RDS(on) ranges. Their superior silicon technology and package design deliver exceptional switching and EMI performance, making them particularly useful in switching and PWM control applications, as demonstrated by early customer success. They also simplify design, eliminate the need for additional passive components, and overall enable electronics manufacturers to better serve high-current markets. Compared to other discrete packages, they significantly reduce the number of parallel MOSFETs required for high-current applications, resulting in lower overall system costs.

Fairchild's TO-LL portfolio currently consists of 40V, 60V, 80V and 150V ratings, with a 100V product coming soon.
