Single-chip load switch ICs reduce power consumption
Featuring on-resistance ratings down to just 63mΩ, three single-chip load switch ICs have been introduced by Toshiba Electronics Europe. The TCK106AF, TCK107AF and TCK108AF integrate high performance chips in an industry-standard SOT-25 package and offer low typical quiescent currents of 110nA with low loss, low standby current and high performance switching characteristics.
Fabricated using a Toshiba CMOS process that combines an output transistor and an output driver, the single-chip IC load switches provide a smaller footprint than switches composed of multiple discrete components. This makes them suited 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- and N-ch MOSFETs, Toshiba’s load switch ICs reduce system power consumption via power supply distribution or power supply control for each function block. They allow for low-leakage load switching, while maintaining a low on-resistance.
All three ICs are housed in a general-purpose SOT-package measuring 2.9x2.8x1.1mm.
