Choosing an Appropriate Pull-up/Pull-down
... The first thing to recognize when dealing with an open drain output is whether a pull-up or a pull-down resistor is needed. This depends on whether the IC drives the output high or low when it wants to assert it. For example, the TPS62067 step-down converter has a PG output that it drives low if the ...
