I was building a bootstrap based gate driver for BLDC motor control application.From this application note (https://www.infineon.com/dgdl/Infin...N.pdf?fileId=5546d4626c1f3dc3016c47de609d140a) I came to know that charge pump is required for continuous turning on of high side MOSFET. They have demonstrated the same using a circuit also.But I need some clarity in this regard. Here it is stated the timer will output a 7.5kHz square wave with 15V amplitude.How is this 7.5kHz designed.?Does this value have any significance.I need to switch my device at 100kHz. Is this frequencies correlated.Also my Mosfet require a gate voltage of 6V only.So should i use 6V zener to achieve the required amplitude.
