Fabricated using a CMOS process that combines an output transistor and an output driver, the new single-chip IC load switches provide a smaller footprint than switches composed of multiple discrete components, suiting them to space-critical applications. The TCK106AF, TCK107AF and TCK108AF help reduce power consumption in devices such as industrial tablets, M2M modules and other portable battery operated equipment.
Additionally, with integrated slew rate control drivers and low on-resistance P-ch MOSFETs and N-ch MOSFETs, Toshiba’s load switch ICs are claimed to reduce system power consumption via power supply distribution or power supply control for each function block. They are said to allow for low-leakage load switching, while maintaining a low on-resistance. All three ICs are housed in a general-purpose SOT-package measuring 2.9 × 2.8 x 1.1mm.
