Toshiba Electronics Europe TCK421G
MOSFET gate driver IC
The MOSFET gate driver IC TCK421G controls the gate voltage of external N-channel MOSFETs based upon the input voltage.It is suitable for configuring a power multiplexer or a load switch circuit equipped with reverse-current blocking by being combined with a back-to-back connection of external N-channel MOSFETs.
Housed in the chip scale WCSP6G package,the device has a footprint of just 1.2mmx0.8mm and a height of 0.35mm.This is one of the smallest packages in the industry and allows use in densely packed devices such as wearables and smartphones.The TCK421G is the first product launched in a series that will eventually comprise six devices.
