Application Note
1. Application circuit example (top view)
The figure below shows the recommended configuration for TCK206G, TCK207G and TCK208G.
1) Input capacitor
An input capacitor (C
IN
) is necessary for the stable operation of TCK206G, TCK207G and TCK208G. And it is
effective to reduce voltage drop due to sharp changes in output current and also for improved stability of the power
supply. When used, place C
IN
more than 1.0 μF as close to V
IN
pin to improve stability of the power supply.
2) Output capacitor
An output capacitor (C
OUT
) is not necessary for the guaranteed operation of TCK206G, TCK207G and TCK208G.
However, there is a possibility of overshoot or undershoot caused by output load transient response, board layout
and parasitic components of load switch IC. In this case, an output capacitor with C
OUT
more than 0.1μF us
recommended.
3) Control pin
A control pins for TCK206G and TCK207G are both Active High and TCK208G is Active Low. These controls
both the pass-through n-ch MOSFET and the discharge n-ch MOSFET (except TCK206G), operated by the control
voltage and Schmitt trigger. When the control voltage level is High (Low; TCK208G), Output n-ch MOSFET is ON
state and discharge n-ch MOSFET is SW OFF state. When control voltage level is Low (High; TCK208G), and the
state of the MOSFETs is reversed. Also, pull down resistance equivalent to a few MΩ is connected between
CONTROL and GND, thus the load switch IC is in SW OFF state even when CONTROL pin is OPEN(except
TCK208G). In addition, CONTROL pin has a tolerant function such that it can be used even if the control voltage is
higher than the input voltage.
2. Reverse current blocking
Reverse current blocking(SW OFF state) function is designed in these products. This function is active at output
n-ch MOSEFT turned off.
However these does not assure for the suppression of uprising device operation. In use of these products, please
read through and understand dissipation idea for absolute maximum ratings from the above mention or our
‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum ratings in any condition.
Furthermore, Toshiba recommend inserting failsafe system into the design.
