Choosing an Appropriate Pull-up/Pull-down
... When finding the minimum value for RPull-up, it is assumed that Q1 is turned on as shown in Figure 2, so VPG is shorted to ground. In reality, Q1 has a resistance, RDSon, which will drop some voltage and cause the PG voltage to be above ground potential. When Q1 is on, the PG voltage must be suffici ...
