1.7.3 MOSFET Voltage Clamp Setup

When using DOUT to drive an N-Channel MOSFET set the specic DOUT pin action to "Over

Voltage" and check the "inverted" option in Ion Studio.

1.7.4 MOSFET Voltage Clamp Wiring

Alternatively a solid state switch (Q1) can be used along with the power resistor(R3) for higher

current requirements. Wire the circuit as shown below. Q1 should be a 5v logic level N-Channel

MOSFET. An example would be the FQP30N06L. It is rated to a maximum voltage of 60VDC. You

may need to change the MOSFET used based on the application. The gate of the MOSFET must

be connected to a DOUT pin along with a 5VDC pull-up resistor.
