Drive device for switch for electronic switching of loads has semiconducting bridge circuit with clock signal input, charge pump with 42 Volt supply for generating gate voltage for FETs

摘要

The switch has a one or more field effect transistors or FETs (T3) connected in series between an operating voltage source and the load. The device has a semiconducting bridge circuit (HB) and a charge pump (L) to generate the gate voltage for the FETs. The bridge circuit has a clock signal input (E1) and the charge pump has a first supply voltage connection (K1) for a supply voltage of 42 Volts. Independent claims are also included for the following: an arrangement for implementing the method.
