Load-switch IC offers on-resistance of 18.4 milliohms
The TCK20xG load switch series claims the industry’s lowest ON resistance of 18.4 mΩ at an input voltage of only 0.75V, the minimum input voltage; output current handling is up to 2 A. The typical standby and quiescent currents in the range of 1 µA and 20 µA together with the minimum ON resistance ensure switch IC operation with minimal power consumption and loss.
There are three models in the series – the TCK206G, TCK207G and TCK208G – offering different output discharge and control pin configurations. The TCK207G and TCK208G feature an integrated output discharge function, with “active high” and “active low” control pin, respectively, whereas the TCK206G omits the discharge function offering a pull down (active high) control pin. All three versions have additional integrated features such as a reverse current blocking circuit and a control circuit with inrush current limitation.
Housed in ultra-small WCSP4C packaging, the devices measure 0.9 x 0.9 x 0.5 mm.
