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 (pA level) when the control pin is 鈥渙ff.鈥?The impedance
on the output side is high and the reverse current does not
flow when the control pin is 鈥渙ff.鈥?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 recommended, this
package is capable of dissipating up to 350 mW.
