TCK106AG/TCK107AG/TCK108AG 2015-10-05 5 Application Note 1. Application circuit example (top view) The figure below shows configuration example for TCK106AG, TCK107AG and TCK108AG. 1) I nput capacitor An input capacitor (C IN) is not necessary for the guaranteed operation of TCK106 AG, TCK107AG and TCK108AG. However, the use of CIN 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 CIN as close to VIN pin to improve stability of the power supply. Also, due to the C IN selected, VIN < VOUT may occur, causing a reverse current to flow through the body diode of the pass -through p-ch MOSFET of the load switch IC. In this case, a higher value for C IN as compared to CL is recommended. 2) Output capacitor An output capacitor ( C OUT) is not necessary for the guaranteed operation of TCK106 AG, TCK107AG and TCK108AG. 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 COUT more than 0.1μF us recommended. 3) Control pin A control pins for TCK106AG and TCK107AG are both Active High and TCK108AG is Active Low. These controls both the pass-through p-ch MOSFET and the discharge n-ch MOSFET ( except TCK106AG), operated by the control voltage and Schmitt trigger. When the control voltage level is High (Low; TCK108AG), p-ch MOSFET is ON state and n-ch MOSFET is OFF state. When control voltage level is Low (High; TCK108AG), and the state of the MOSFETs is reversed. Also, pull down resistance equivalent to a few M Ωis connected between CONTROL and GND, thus the load switch IC is in OFF state even when CONTROL pin is OPEN(except TCK108AG) . 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.
