TK70001
SINGLE INPUT, TWO OUTPUT SOLID STATE SWITCH
FEATURES
■ Internal PNP Power Transistor
■ Reverse Bias Voltage Protection
■ Very Low Input-Output Voltage Difference
■ Very Low Standby Current
■ Overtemperature Protection
■ Single Input with Two Controlled Outputs
■ Low Noise
DESCRIPTION
The TK70001 is a monolithic bipolar integrated circuit with
high side current switches of low saturation type. The
current, including the control current, is 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 TK70001 a very efficient
device for power management and power distribution
control.
APPLICATIONS
■ Battery Powered Systems
■ Radio Control Systems
■ Automatic Test Equipment (ATE)
■ Power Management
■ Process Control Equipment
■ Power Distribution Control
■ Communication Equipment
