The TK70002 is a monolithic bipolar integrated circuit with high side current switches of low saturation type. The supply current, including the control current, is virtually zero (pA level) when the control pin is "off". The impedance on the output side is high and the reverse current does not flow when the control pin is "off." These are effective to decrease the dissipation currents, making the TK70002 a very efficient device for power management and power distribution control.
