TK70003
20P
SINGLE OUTPUT, TWO INPUT 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 Output with Two Controlled Inputs
■ Active High On/Off Control
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 “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 recommended, this
package is capable of dissipating up to 350 mW.
APPLICATIONS
■ Battery Powered Systems
■ Radio Control Systems
■ Automatic Test Equipment (ATE)
■ Power Management
■ Process Control Equipment
■ Power Distribution Control

Note 1: Power dissipation is 350 mW when mounted as recommended. Derate at 2.8 mW/°C for operation above 25 °C. Power
dissipation is 150 mW in Free Air. Derate at 1.2 mW/°C for operation above 25 °C.
Note 2: By grounding this terminal, the operation completely stops and the input current decreases to a pA level.
Note 3: Ground current is defined as IIN - I
Note 4: If both input voltages are the same (parallel operation), both switches can be turned on at the same time. If the input voltages
are different, only one switch should be turned on at any given time.
Gen. Note: Parameters with min. or max. values are 100% tested.
Gen. Note: Exceeding “Absolute Maximum Ratings” can damage the device.
