MOSFET Gate Driver IC Overview

MOSFET Gate Driver IC is an ON and Off switching control device for external N-channel MOSFET. Toshiba MOSFET Gate Driver ICs have charge pump and protection circuits and they feature ultra small package (1.2 × 0.8 mm), low quiescent current and wide input voltage. Using them with N-channel MOSFET, this solution acheives small size and low loss power line. Toshiba have a variety lineup of Over Voltage Lock Out function.
