Driver for switch for electronically switching load has half bridge circuit, charge pump using processor generated clock signal to generate rectangular wave gate voltage for switching FET

摘要

The driver has a half bridge circuit (HB), a charge pump (L) and an input connected to a processor (P) output at which a clock signal (CK) is produced that s used in conjunction with the half bridge circuit and charge pump to generate a rectangular wave gate voltage with a frequency off the order of 100 KHz for switching the FET or FETs into the conducting state.
