High side gate drive output
Weblized as a high side switch (drain connected to the high voltage rail, as shown in Figure 1) driven in full enhancement, i.e., lowest voltage drop across its terminals, can be summarized as follows: 1. Gate voltage must be 10-15V higher than the drain voltage. Being a high … WebAs seen in Figure 4, high-side on-resistance and the external series resistor R EXT form the gate resistor in the charging path, and low-side on-resistance with R EXT forms the gate resistor in the discharging path. …
