I would like to increase the maximum current that a PWM signal from a microcontroller can deliver from +-25mA to +-500mA. See image below. The output should have the same peak-to-peak voltage (0 to 3.3V) and should not be inverted (i.e. follows the input). I have looked into using an active push-pull output but the only configurations I can find is inverting (see image below). First, does anyone have suggestion on a digital push-pull circuit that will fit my needs? Also, is there a single chip solution to achieve this? I would prefer the circuit stay low cost and have a small footprint (for example sot-23).
Any help would be great.
