Toshiba Ships Samples of Industry's Lowest ON Resistance Load Switch ICs

Featuring Reverse Current Blocking in Ultra-Small Package

IRVINE, Calif., Nov. 12, 2013 — (PRNewswire) — Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced that it began shipping samples of three new ultra low voltage load switch ICs that feature the industry's smallest[1] switch ON resistance.  The TCK206G, TCK207G and TCK208G join Toshiba's broad lineup of load switch ICs for mobile devices.

With an embedded reverse current block (RCB) circuit and a slew rate control driver, the TCK206G, TCK207G and TCK208G are designed for use as a power management switch IC in smartphones, tablets, ultrabooks, and other mobile equipment.  The new products feature very low ON resistance and very low input operating voltage, in an ultra compact package, which was achieved using Toshiba's newly developed CMOS process and unique analog circuit design techniques.

As mobile devices trend towards higher battery capacityand become smaller and lighterthere is an increased demand for ultra-compact, low power consumption, low power dissipation switches.  Available in a 0.5mm pitch WCSP4C package, the TCK206G, TCK207G and TCK208G are ideal for portable applications that require high-density board assembly.

Key features include:

  • Low input voltage operation: V(IN)=0.75 to 3.6V
  • Low ON resistance:
    R(ON)=18.1m ohms (typ.) @V(IN)=3.3V, I(OUT)=-1.5A
    R(ON)=18.2m ohms (typ.) @V(IN)=1.2V, I(OUT)=-1.5A
    R(ON)=18.4m ohms (typ.) @V(IN)=0.75V, I(OUT)=-1.5A
  • Inrush current is limited by the slew rate control driver
  • Reverse current blocking
  • Built in Auto-discharge (TCK207G and TCK208G)
  • Ultra small package: WCSP4C (0.9mm×0.9mm, t: 0.5mm(typ.))
