TK70002
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
■ Active High On/Off Control
DESCRIPTION
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.
APPLICATIONS
■ Battery Powered Systems
■ Radio Control Systems
■ Automatic Test Equipment (ATE)
■ Power Management
■ Process Control Equipment
■ Power Distribution Control
