v1.0 Typical Application Circuits INPUT Pins
The MM9200 WL-CSP package has multiple input pins named INPUT, QFN package has only one. In the WF-CSP, they are internally connected inside the package; however, they shall be externally connected in the application as close as possible to the package.
OUTPUT Pins
The MM9200 WL-CSP package has multiple output pins are named OUTPUT, QFN package has only one. Like the WL-CSP package INPUT pins, they are internally connected inside the package and shall also be externally connected in the application as close as possible to the package.
GATE Pin
The gate pin is connected to the electrostatic actuation electrode used to close the two switch elements. The counter electrode is connected to the MIDPOINT pin that serves as the reference voltage for the actuation voltage applied at the GATE pin. The allowable voltages on the GATE pin are 0 V and 90 V (nominal, see VGATE specification).
MIDPOINT Pin
To ensure that the MIDPOINT pin operates at the correct DC voltage based on the INPUT and OUTPUT pin DC voltages, it is recommended to use a resistive divider as shown in Figure 9. This ensures that the DC voltage applied to the MIDPOINT pin is correct for the Off/open state, as well as for proper switch actuation and On/closed state closure.
