There are many other bridge circuits made of different components and with different uses. The H bridge gets its name from looking like an H.

I've seen other circuits that have a series of components between power and ground called 'totem pole' as well.Ī 'half bridge driver' is called that because it's half of a 'full bridge driver', also known as an H bridge.

(power, resistor, transistor, diode, transistor, ground). 'Totem Pole' is named such because the classic TTL output driver somewhat looks like the tall vertical statues, because of the 4 elements stacked vertically between power and ground. It might help to know what the names refer to.
