Re-packaging MOSFETs for space-limited product designs

June 05, 2013 // By Paul Buckley
ON Semiconductor has introduced two new MOSFET devices designed for use in appications such as smart phones and tablet PCs applications where they provide part of the Lithium ion (Li-ion) battery charging / discharging protection circuit switching.

The EFC6601R and EFC6602R help designers to reduce solution size, improve efficiency and maximise battery life. Suitable for single or dual Li-ion cell implementations, they offer industry-leading levels of RDS (on) performance and employ a Land Grid Array (LGA) structure to give them a small, low-profile design that makes them ideal for limited space environments. The EFC6601R has a specified maximum VSSS (Source to Source Voltage) of 24 V, and the EFC6602R has a specified maximum VSSS of 12 V. Both devices operate from a 2.5 V supply, have a common-drain structure, and a built-in protection diode.
ON Semiconductor plans to add five further devices to the EFC MOSFET family within the year that will help designers of an even wider range of mobile devices achieve their application objectives for reducing solution size and extending battery life.
The EFC6601R and EFC6602R, in EFCP packages, cost $0.80 and $1.00 (5,000).
