Totem Pole Circuit Working. Now assume that the input terminals a and b are together and a trigger pulse applied to it. A low side drive circuit which drives the low side power device.
Totem pole basically an output driver circuit use to convert one level of voltage into another level of voltage. Totem pole push pull output stages two matched transistors of the same polarity can be arranged to supply opposite halves of each cycle without the need for an output transformer although in doing so the driver circuit often is asymmetric and one transistor will be used in a common emitter configuration while the other is used as an emitter. Since the collector voltage of t 2 v c2 v cc transistor t 3 turns on and it acts as a short circuit between v cc and output point z.
For example you want to drive gate of mosfet with the help of microcontroller output pin the microcontroller output pin is generating a square wave of voltage level 5 volt and to fully drive mosfet gate of p channel mosfet you need to provide 12 volt at the gate of p channel mosfet.
Reason for using the totem pole output configuration. Sreejith hrishikesan september 06 2018. Reason for using the totem pole output configuration. 3 5 which shows t3 one of the totem pole output transistors being replaced with a load resistor rl.
