Component Selection
It is advisable to decouple the ZXGD3101 closely to V
The proper selection of external resistors R
reference current, I
provides a recommended typical offset voltage of ~20mV.
External gate resistors are optional. They can be inserted to control the rise times which may help with EMI issues, power supply consumption
issues or dissipation within the part.

R
Layout considerations
The Gate pins should be as close to the MOSFET Gate as possible. Also the ground return loop should be as short as possible. The decoupling
capacitor should be close to the V
For more detailed information refer to application note AN54..
