DESCRIPTION
The TK70003 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 (p A 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 TK70003 a very efficient device for power management and power distribution control. The TK70003 is available in a miniature SOT-23-6 surface mount package. When mounted as remended, this package is capable of dissipating up to 350 m W. TK70003
