7.3.2 Output Stage

LMG1020 provides 7-A source, 5-A sink (asymmetrical drive) peak-drive current capability, and features a split output configuration. The OUTH and OUTL outputs of the LMG1020 allow the user to use independent resistors connecting to the gate. The two resistors allow the user to independently adjust the turnon and turnoff drive strengths to control slew rate and EMI, and to control ringing on the gate signal. For GaN FETs, controlling ringing is important to reduce stress on the GaN FET and driver. The output stage OUTL is also pulled down in undervoltage condition, which prevents the unintended charge accumulation of device Ciss.
